[t5] upgrade to java 6 and javassist
I've been struggling the last few days to upgrade to java 6 and get my
tapestry 5 app to work. Everything starts up nicely but when accessing a
page I get the below listed exception. It seems to have to do something
with javassist as also some internet resources suggest, but I didn't
find any solution. Has anyone encountered this and can they point me in
the right direction?
I use T 5.2.0.0-SNAPSHOT and javassist:javassist 3.11.0.GA
Cheers,
Joost

Thx for this feedback.
I am still a bit puzzled by the whole thing but encouraged enough by your
and Gunters tips to not yet drop T5 and switch to Wicket.
Much appreciated.

Example:
@OnEvent(EventConstants.PROVIDE_COMPLETIONS)

Re: [t5] upgrade to java 6 and javassist
Posted by Inge Solvoll <in...@gmail.com>.
This is embarrassing.
Our most recent problems with javassist crashes were entirely our own fault,
not javassist or t5. We had a search/replace ant target that replaced all
occurrences of "/script" with "/script<todaysdate>". This target recursed
(not our intention) into our classes folder, and did some replacement on
class files, the ones that got crashes from javassist. It seems that the
value of the @IncludeJavascriptLibrary and other annotations are stored as
pure readable text in the compiled file.
I believe our earlier problems with javassist were real, due to things like
1.6 as compilation target, duplicate javassist.jar in classpath and so on.
But this last one was a big stupid mistake. I wanted to report it here to
avoid people using my case in the future as proof in similar issues. As of
now, we have no issues with javassist in T5.
Sorry, guys!

Re: [t5] upgrade to java 6 and javassist
Posted by Howard Lewis Ship <hl...@gmail.com>.
I'm very glad you found a solution ... it's still a mystery to me as
all the applications I work on are built using the Sun javac compiler
and I've never seen problems like you are seeing, and I do some of my
deployments on Linux (Ubuntu) ... again, with the Sun JDK/JRE.

Re: [t5] upgrade to java 6 and javassist
Posted by Inge Solvoll <in...@gmail.com>.
2 more days spent on this, and I actually came up with a solution: Switching
from JDK "modern" compiler to eclipse compiler. I found another thread about
class transformation errors on the list, saying that the Java C compiler had
issues with class transformation.
http://www.mail-archive.com/users@tapestry.apache.org/msg23610.html
I rebuilt my classes with the eclipse compiler, and voila! No more errors
about invalid constants and similar!
The recipe for using eclipse compiler in ant:

Re: [t5] upgrade to java 6 and javassist
Posted by Inge Solvoll <in...@gmail.com>.
Done some pretty extensive research on this the last few days. Our
application doesn't work at all on our test and production servers, because
of the dreaded "invalid constant length" error.
We have the following setup:
- jre-6u16 for linux
- Suse Linux
- JBoss 5.0.1 with embedded tomcat
- Compiles using java 1.6, tried both 1.5 and 1.6 as target compatibility
I have verified that there is excactly ONE javassist.jar within my jboss
directory, and the version of that file is 3.9.0.GA.
I still get javassist crashes on several of my smaller components, like the
one below. I'm going crazy over this, especially because it indicates to
everyone else that our big investment in T5 may have been a really stupid
move.
Just reported this to let you know that this problem DOES occur when there
is only one javassist.jar, and it is causing major problems for us.
Example of crashing component:
@IncludeJavaScriptLibrary( { "context:/script/tiny_mce/tiny_mce.js" })
public class TinyMceEditor {
public static final String MODE_EXACT = "exact";
public static final String MODE_TEXTAREAS = "textareas";
@Inject
private UrlProvider urlProvider;
@Environmental
private RenderSupport renderSupport;
@Parameter(defaultPrefix = BindingConstants.LITERAL, value =
MODE_TEXTAREAS)
private String mode;
/**
* If mode=exact, attach editor to these elements
*/
@Parameter
private ClientElement[] elements;
void initEditor(MarkupWriter writer) {
// We can't use renderSupport to add script, tinyMCE refuses to accept
// scripts added this way. It needs inline script. Script tag written
// manually below.
String jsonString = getJSON();
writer.element("script", "type", "text/javascript");
writer.writeRaw(String.format("tinyMCE.init(%s)", jsonString));
writer.end();
}
/**
* Make sure editor content is saved to form field before Tapestry AJAX
* submits.
*/
void patchZoneForms() {
renderSupport.addScript("document.forms[0].observe(Tapestry.FORM_PROCESS_SUBMIT_EVENT,
function() {tinyMCE.triggerSave()});");
}
/**
* Get JSON config for tinyMCE object. Configured to view one simple
toolbar.
*
* @return
*/
private String getJSON() {
JSONObject json = new JSONObject();
json.put("mode", mode);
json.put("theme", "advanced");
addElementList(json);
json.put("theme_advanced_toolbar_location", "top");
json.put("theme_advanced_toolbar_align", "left");
json.put("theme_advanced_buttons1",
"bold,italic,underline,bullist,numlist,undo,redo,outdent,indent,fontsizeselect");
json.put("theme_advanced_buttons2", "");
json.put("theme_advanced_buttons3", "");
json.put("content_css",
urlProvider.getContextAssetUrl("/css/tinymce.css"));
return json.toString();
}
private void addElementList(JSONObject json) {
if (MODE_EXACT.equals(mode)) {
if (elements != null && elements.length > 0) {
StringBuffer elementsString = new StringBuffer();
for (int i = 0; i < elements.length; i++) {
ClientElement currentElement = elements[i];
FrontendTools.appendCommaSeparated(currentElement.getClientId(),
elementsString);
}
json.put("elements", elementsString);
}
else {
throw new IllegalArgumentException("Exact mode specified, but no
elements");
}
}
}
void afterRender(MarkupWriter writer) {
initEditor(writer);
patchZoneForms();
}
}

Inge

Posted by Fermin Da Costa Gomez <da...@dcgconsultancy.nl>.
For what it is worth .. i have not had *this* problem anymore since i
straigthened out the use of the libs in the different projects being used.

Re: [t5] upgrade to java 6 and javassist
Posted by Inge Solvoll <in...@gmail.com>.
This problem has been gone for us for a while, today it came back when
deploying our app to a jboss server (5.0.1) with embedded tomcat. I
immediately started searching for javassist.jar duplicates. Found
javassist.jar in jboss/lib, jboss/client and <myapp>/WEB-INF/lib.
Jboss wouldn't start up without the one in jboss/lib, so I removed all but
that one. Now it started, and my T5 app works, but the error in one specific
component is still there: java.io.IOException: invalid constant type: 121.
It always happens with the same component. The component works in most
configurations, just not on our jboss server setup with embedded tomcat.
I then replaced the javassist.jar in jboss/lib with a fresh 3.9.0, like
specified in this thread. Now Jboss won't start up, nothing happens in the
log when I try to start it
We will continue working on this this week, as this is a major problem for
us. Hopefully, you're right about it being a javassist.jar duplicate issue.
But so far, I haven't found anything pointing in that direction.

Re: [t5] upgrade to java 6 and javassist
Posted by Fermin Da Costa Gomez <da...@dcgconsultancy.nl>.
This was actually it.
A 'hidden' antiquated version of javassist somewhere on the classpath AND
(as later turned out) a project that did not want to be placed on the
classpath (via the classpath settings in the launcher of Eclipse Galileo).
Finally got the whole thing stopping on my breakpoint again ..
I guess it all has to do with the infamous medal ansd its two sides. Having
all the libs available is a good thing but it might also be lurking behind a
tree with dubious intentions .. ;-)
Thx to the list for getting me on my way again.

Re: [t5] upgrade to java 6 and javassist
Posted by Peter Stavrinides <P....@albourne.com>.
Tapestry works perfectly with Java 6 now!!
Lets not be ridiculous and claim that you need to shorten methods and method names etc in order to get it working, it has been completely compatible for some time now. This is a library issue, you must use 3.9.0.GA, which is the version provided by Tapestry 5.1, beware of Chenillekit it brings in an old version javassist 3.7, which in most causes this problem.
You must include this in your pom:
<dependency>
<groupId>org.chenillekit</groupId>
<artifactId>chenillekit-tapestry</artifactId>
<version>1.2.0</version>
<exclusions>
<exclusion>
<groupId>jboss</groupId>
<artifactId>javassist</artifactId>
</exclusion>
</exclusions>
</dependency>

What do you mean by ready-made? EventConstants is just a class that

Howard, the framework creator and main committer, has plans to stop using
Javassist to do the class manipulation used in Tapestry. If you want to

Again, I have never had this issue. I had just checked that all my

I hear what you say but and will try your suggested solution but you would
agree that this is slightly ridiculous!
What is the point of a modern tool if we are to be again bound by using
variables/ methods of a maximum length.
W'r talking a 64b system not an old ms-dos machine with 640K memory ..
We use several strategies to "fix" the problems:

I will keep your recommendations in mind and try to work them into the thing
i'm working on.

Really appreciate your feedback and suggestions and i will try to implement/
use them, although it does seem to go a long way in defeating the whole
purpose or at least some important strong parts of T5.
I am a consultant/ problem solver (sw developer) mainly focussing on the
investment banking/ insurance and for my hourly rate (200+) my clients
expect solid advice. I was planning on working T5 into my solutions but
with this erratic behaviour i can in all honesty not do that. I would even
have to advice against actually using it in production environments.
Please take note of the fact that i still prefer the framework above any
other but having to navigate around these icebergs is not something one
should want ..
If given a choice between documentation and resolving this particular issue
i would always opt for the resolution of the issue. I would even be willing
to make a montary donation to get it out of the way!
Got it out of my system now.

We use several strategies to "fix" the problems:

* reduce the number of @Inject

Once, we were successful by replacing an

It is starting to look like something 'funny' with the Autocomplete class
Relevant tml code:
...
<input t:id="fieldName" t:mixins="autocomplete"
t:type="TextField" />
...
Without the mixin i am able to create 2 exceptions, both pointing to the
Autocomplete class.
When i start without the t:mixin all is fine.
Insert the t:mixin and refresh (the browser) gives the exception below.

(_$assetSource, _$baseResource, _$environment, _$operation, _$resources,
_$type) that are not private. You should change these fields to private, and
add accessor methods if needed.
Restart the server (Tomcat 6.0.20) with the mixin and the 'normal' exception
occurs:
java.lang.ClassFormatErrorInvalid length 112 in LocalVariableTable in class

Unless anybody has another suggestion i'm starting to lean towards the idea
that the autocompleter is not entirely happy about something.

Nope, not yet so i will give it a whirl. However, wouldn't you agree that
three corrupted projects using three different repositories is a bit
suspect?
I hope that that is the problem ..
Thx for the feedback ..

Have you tried deleting the tapestry-core JAR from your local repository
and running a Maven goal (such as compile) again, so the JAR is
redownloaded? Corrupted and/or truncated JAR files provide us all kinds of
random-looking problems and strange behaviours.

Hmm, i figured as much so i did some stripping. Below the code that i end up
with whilst still throwing the error.
How much shorter does it have to be .. ;-)
public class Search {
public List<String> onProvideCompletionsFromFieldName(String partial) {
return new ArrayList<String>();
}
void onValidateForm() {
}
Object onSuccess() {
return this;
}
private List<Object> _results;
public List<Object> getResults() {
return _results;
}
@Log
void setupRender() {
}
}
I don't have any estimate for that. Just take a look at the Tapestry page
> that has that problem and try to shorten their event handler methods.

As you can tell i went a bit overboard but i'm starting to think that the
problem is not in the code but something that's going on in the
AutocompleteMixin, or so it seems to me at least.
To be complete the .tml code as well
...
<form t:type="form" t:id="mixinform">
Type in your search arguments:
<input t:id="fieldName" t:type="TextField"
t:mixins="autocomplete"/>
<br/>
<input type="submit" value="Search"/>
</form>
...
The combo of the above code gave me the following trace (top part ..)
java.lang.ClassFormatErrorInvalid length 112 in LocalVariableTable in class
file org/apache/tapestry5/corelib/mixins/Autocomplete
Hide uninteresting stack frames Stack trace

Is there any chance i'm looking at a 'corrupted' class of sorts, even though
the whole thing is based on the quickstart archetype from Maven.
Or doesn't T5 like Ubuntu on a MacPro .. ;)

I don't have any estimate for that. Just take a look at the Tapestry page
that has that problem and try to shorten their event handler methods.

Sorry if this sounds like a silly question, but what would be an example of
an eventhandler method?
Would that be something like the onSuccess() method .. ?
Large can be defined as >100 chars, >150 chars .. what would you estimate
your avg method size would be, from your experience and the fact that you do

I'm working full time in a Tapestry project using Java 6 without any
problems, so do the right thing :) and refactor any large event
handler methods to smaller ones.

What I need to do is, over time, replace the APIs that are "thin wrappers"
on Javassist with a different high-level set of operations that can be
implemented on top of ASM (likely) instead, then deprecate the Javassist
versions, then eliminate them. See you in Tapestry 5.5 or so! :-)

Hi Joost,
Did you get this 'sort-off' resolved?
A large method constitutes a method with 'a lot of code' or a method with a
long name (fully qualified ..)?

That is all a bit too uncertain for me. I'll revert back to java 5 as I
have no immediate need for 6 in this project. Do you know what the
javassist roadmap looks like and if they are working on propper java 6
support?

Does that regret lead you to make any changes to T5 in the future or is
javassist used so much that that is unrealistic?

Re: [t5] upgrade to java 6 and javassist
Posted by Howard Lewis Ship <hl...@gmail.com>.
Look for any large methods that are annotated or are event listeners and
refactor them to be smaller; too often Javassist gets confused with large
methods.
My biggest regret for Tapestry 5: Should have ditched Javassist, much as I
like it.
