RE: T5: NPE in Base64InputStream and locked/waitingCheckForUpdatesFilter
If you are running under jdk 6u1 and tapestry 5.0.5 (or greater) then
there is
a jvm bug that can cause a deadlock.
The bug report is at
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6571733.
It is supposed to be fixed in jdk 6u2 (which was release recently) but I
haven't had a chance to test it yet.
cheers

RE: T5: NPE in Base64InputStream and locked/waitingCheckForUpdatesFilter
Posted by Ben Sommerville <be...@bulletproof.com.au>.
I finally had a chance to test this & I'm confident it is fixed.
Under 6u1 I was consistently getting a deadlock, under 6u2 I cannot
reproduce it.
cheers

http://tacos.sourceforge.net/tacos4.1/
Igor Drobiazko and myself have been putting a fair amount of work on the
project.
Additionally, Daniel Gredler has donated the beanform code (
http://beanform.sf.net/)
which has been updated and tested with Tapestry 4.1.2 and
Norbert Sandor the tapdoc code (
http://www.erinors.com/developer/project/tapdoc/) so tacos is
currently a merge of all the above :)
There's an internal schedule for a release for 10-15 Aug, but one can safely
use the snapshot jars.

hi,
i am wondering why there is no documentation for the tree-component on:

even though these components are still included into tapestry-contrib-4.1.2.jar. is this legacy-support, or are they just missing?

RE: T4.1.2 error loading hivemind-service
Posted by Ma...@bmw.ch.
javassist changed its group / artifact id from javassist.javassist to jboss.javassist. Release 3.0 was the last one available under the javassist toplevel-group. If you somehow, transitively, reference both, maven has no way to know that both are the same artifact.

Hi
You can check
mvn dependency:analyze
It might happened that there is something else that is using wrong
Javassist version.

AW: T4.1.2 error loading hivemind-service
Posted by Peter Schröder <Pe...@freenet-ag.de>.
it seems that this is a maven-issue. i have to update all dependencies that are still using javassist-3.0 to use javassist-3.4.ga. locally overriding javassist-version in the application pom has no effect... even though eclipse sais, that javassist-3.4.ga is included as a dependency?!!?!?!?!?

hi renat,
i am using maven for my dependency management. it automatically includes javassist-3.4.ga.jar into my project. this is the same version that is stated here:
http://tapestry.apache.org/tapestry4.1/dependency-convergence.html
i thought that hivemind services are compatible within T4 and T4.1.2. (at least, i did not read the opposite somewhere), cause both use hivemind-1.1.1?!
kind regards,
peter

Hi
This exception
"javassist.CtClass.toClass(Ljava/lang/ClassLoader;Ljava/security/ProtectionDomain;)Ljava/lang/Class;"
Means that you have a Javassist version mismatch, check your classpath
for the older versions of Javassist.

T4.1.2 error loading hivemind-service
Posted by Peter Schröder <Pe...@freenet-ag.de>.
hi,
i am doing a simple test with the new version of tapestry (runs fine with 4.0.2):
public class LoginTest extends TestCase {
public void testService() {
Registry registry = RegistryBuilder.constructDefaultRegistry();
AGLoginService service = (AGLoginService) registry.getService(AGLoginService.class);
boolean isAdmin = false;
ArrayList<String> ldapRoles = new ArrayList<String>();
ldapRoles.add("admin");
String userName = "dummyuser";
String userPassword = "xyz";
service.authUser(userName, userPassword, ldapRoles, isAdmin);
}
}
resulting in the following stacktrace using javassist-3.4.ga. i also tried to use an old version of javassist (3.0) wich doesnt work either...

RE: T5: NPE in Base64InputStream and locked/waitingCheckForUpdatesFilter
Posted by Ben Sommerville <be...@bulletproof.com.au>.
One work around that I found is to create the read/write lock in
ConcurrentBarrier in "fair" mode instead of the default mode.
(fair mode changes the algorithm used to decide which thread
gets the lock next)
That worked for me but subjectively things seemed a little slower
(no actual measurement so take that for what it is worth)
If it is fixed in 6u2 then I'd be tempted just to document the
problem with 6u1 :)
cheers
Ben
PS: I'll try to actually confirm that is it fixed in the next
few days... may not get to it till the weekend tho

RE: T5: NPE in Base64InputStream and
locked/waitingCheckForUpdatesFilter
Posted by Martin Grotzke <ma...@javakaffee.de>.
Ben, thanx a lot for this info!
We were running our app under jdk 6u1 and tapestry 5.0.5, so it's
matching perfectly.
I just installed jdk 6u2 on our test-system and started our app
with this - so we'll see if it happens again.
I'll give a feedback after say 5 days when our app is fine, or of course
if this problem occurs again.
Btw: it's very amazing communicating on this list, as there's so much
useful and fast feedback - really great!!
Thanx for now,
cheers,
Martin

RE: T5: NPE in Base64InputStream and locked/waitingCheckForUpdatesFilter
Posted by Matt Ayres <ma...@lithium.com>.
I haven't had a chance to run a load test of j6u1 vs j6u2 with 5.0.5,
however switching to j6u2 on our public test site for the last day seems
to have solved the problem. The previous day on j6u1 it stopped
responding 4 times. Thanks for pointing out the bug report.

locked/waitingCheckForUpdatesFilter
If you are running under jdk 6u1 and tapestry 5.0.5 (or greater) then
there is
a jvm bug that can cause a deadlock.
The bug report is at
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6571733.
It is supposed to be fixed in jdk 6u2 (which was release recently) but I
haven't had a chance to test it yet.
cheers
