jchevm status?
I have recently built jchevm and tried to run eclipse with it. When
loading a error window appeared. It looks like a bug or unimplemented
functionality.
I have taken a look at list of loaded native libraries. It looks
classpath is used for system classes instead of harmony classlib. I
remember, there was some discussion about porting jchevm to harmony
classlib, what is the status of this work? Harmony classes prooved to
work in drlvm. So I think once the porting is done it could be
possible to get eclipse working on jchevm soon.

The classpath adapter is very primordial at this point. On the other
hand JCHEVM on Classpath's class library should be fairly mature
(limited mainly by Classpath itself). By comparing the two, as well
as JCHEVM vs. other JVMs that use Classpath, and eventually other
Classpath-based JVM's using the adpater, we'll be able to pinpoint
which parts are (mis)behaving, etc.

I see now. .thanks. Should be fixed in r412122.
FYI the test case depends on how the compiler compiles the bytecode.
The test below would pass when using "javac" but fail with "jikes".
Javac generates GETSTATIC FieldRes$FieldResInterface.FIELD while
jikes generates GETSTATIC FieldRes$FieldResClass.FIELD.
public class FieldRes {
public static interface FieldResInterface {
Object FIELD = new Object();
}
public static class FieldResSuperclass implements FieldResInterface {
}
public static class FieldResClass extends FieldResSuperclass {
}
public static void main(String[] args) throws Exception {
System.out.println(new FieldResClass().FIELD);
}
}

The difference is that access to that field should be done without
reflection. I don't have the jchevm at hand, but I think the
problematic code should look like:
interface I {
static final int field = 123;
}
class S implements I {
}
public static C extends S {
public static void main(String[] args) {
System.out.println(field);
}
}
I didn't tested wether it fails. I will check it when get home.

Do you have a simple test case? This one seems to work OK:
public class FieldRes {
public static interface FieldResInterface {
int field = 123;
}
public static class FieldResSuperclass implements FieldResInterface {
}
public static class FieldResClass extends FieldResSuperclass {
}
public static void main(String[] args) throws Exception {
FieldResClass obj = new FieldResClass();
System.out.println(obj.getClass().getField("field"));
System.out.println(obj.field);
}

Thank you, I will take a look at it at evening (10 hours later)
Btw, I have found problem is classloader in jchevm.
Resolution of field in interface of superclass of some class fails.
Reproducible at eclipse. I have a patch with fix. It's quite simple. I
can send it at evening too.

Looks like you have downloaded recent classlib. This problem appeared
a few days ago after some changes in classlib. I have already created
a patch which adds the methods. Classlib is moving to java5 interfaces
so this changes should also go in the adapter.
There are a bunch of patches already attached to Harmony-483.
Reflection, system classloader works now reasonably well. My main
testing workload is eclipse and I am slowly moving forward. Eclipse
already can successfully use logging. I am investigating why it cannot
load its own jars.
A small note about patch sequence in jira: all patches should apply
cleanly except wrong patch: 2.
classlibadapter-incremental-update-20060522-20060528.diff (163 kb)
It was sent by mistake and contains exact the same content as initial
patch classlibadapter-update-20060522.diff.

That's great news...

Re: jchevm status?

Archie, I have made some progress with classlib adapter. Now eclipse
starts and opens main window, just as with gnuclasspath. It works even
faster then it. Of cause, a lot of functionality is still missing. Now
I found a jchevm issue which prevents eclipse from working both on gnu
classpath and using this adapter. Here is the eclipse code:
private static void checkAccess() throws IllegalStateException {
StackTraceElement[] elements= new Throwable().getStackTrace();
if (!(elements[2].getClassName().equals(EditorsUI.class.getName())
|| elements[3].getClassName().equals(EditorsUI.class.getName())))
throw new IllegalStateException();
}
This code checks access control in eclipse. The caller of the method
should be member function of class EditorsUI. As jchevm also reports
exception creation stack frames the access check doesn't work. I can
make a workaround in classlibadapter, but I think it should be better
fixed in the vm code, as the fix will work with gnu classpath too. If
you are too busy, I can make this fix for jchevm.
Best regards,

Archie,
I tried to build Ivan's mods. I get a bunch of javac compiler errors
starting with, "java.lang.reflect.Constructor is not abstract and does
not override abstract method isSynthetic()..."
Unfortunately, I have zero time to spend on this project right now. I
looked at Ivan's mods. They seem reasonable and valuable. Please use
your best judgement on applying the patches to the code.
I don't want to slow down forward progress on the gnuclasspathadapter
project. It would be great if someone jumps in and take this project
forward.

Sure, you can email them to me. We should add a ./configure flag like
"--disable-optimization" or something that would do this.
In my experience it's fairly rare that I need to disable optimization
because gdb still works well with it (although you have to be aware that
sometimes variables "disappear" etc), but indeed sometimes it's necessary.

Re: jchevm status?
Posted by Ivan Volosyuk <iv...@gmail.com>.
Weldon, I have added patch update to the same JIRA. Recent version of
jchevm and classlib is changed, so old version of the adapter no
longer works.
Archie, current version of jchevm has hard coded optimizations in
configure.ac, it is difficult to debug the code with optimizations.
When disabling optimizations in it (-O0) - there are compilation and
execution problems. I have small fix for compilation problems and
small dirty fix for execution. Interested?

The point is, that I have already signed some papers for my part in

Anyway, I can send ACQ and ICLA via fax tommorow.

Please hold off the check-in for a few days. I would like to try
Ivan's mods on my machine to make certain they are complete. The
intention is to reduce the chance of secondary patch-up check-ins and

Ivan,
I just now looked at 483. Good work. I'd like to check-in these mods
into svn but don't have check-in permission.
I am in the process of trying to move to the current version of
Harmony Class Library. It will also soon need to be checked in. I
will send a mail on it shortly.

If you update make sure you get at least r408953, which contains a bug fix.

Weldon,
I have prepared my modifications and posted a patch against the
SVN/classlibadapter.
http://issues.apache.org/jira/browse/HARMONY-483
I was able to get rid of all native modifications and some of modified classes.
NewWeakGlobalRef implementation on vm needed though.
More tests works when adding in bootclasspath instead of classpath
(system classloader is not quite finished)
Exception traces works and quite useful to find problematic places.

Ivan,
Good progress. Again, it would be helpful for planning if you could
tell us what you would like to work on and how much time you can spend
on it. Currently I am in the process of figuring out how to "borrow"
a bunch of the DRLVM native methods for gnuclasspathadapter. It would
be great if you can help. It may be as simple as 1) build drlvm, 2)
copy DLLs to gnuclasspathadapter directory.
Can you post your mods as a zip file to JIRA?

I've just wanted to check the problem with incorrect interfaces and...
Looks like I suddenly made a good progress:
======= _200_check Finished in 0.012 secs **NOT VALID**
======= _209_db Finished in 43.748 secs **NOT VALID**
======= _222_mpegaudio Finished in 97.589 secs **NOT VALID**
======= _201_compress Finished in 106.233 secs **NOT VALID**
As you can see I managed to run some of specjvm98 tests. :) There are
a lot of validity errors, but its finally passed to the end.
Changes done:
Fixed Class.newInstance(), Constructor.newInstance()
Fixed stack trace display in Throwable
Implemented Runtime.getRuntime()
What a wonderful thing is stack traces! :)

Here is issues I've found:
* There was no build instructions. I assumed that I should place the
adapter separately, as it have 'doit.bat' kind of build files.
* No build files for linux.
* Changes to harmony tree happened so I need to fix some imports in
patched java-files.
* Java files has hardcoded absolute path for glue native library.
* Loading of native libraries is disabled via "Runtime.load()", I used
LD_PRELOAD and modified jchevm to search libraries via
dlsym(RTLD_DEFAULT, "").
* For specjvm98 made number of stubs for java.awt.* classes.
* Java_?_writeImpl() uses libvmi.so functionality which not
implemented in classlib stub. Need to write my own implementation.
* NewWeakGlobalRef used by nio. Changed jchevm to fallback to
NewGlobalRef instead of crash.
* Functionality from HyVMLSFunctionTable is used. Workaround: comment
out java.io.File.oneTimeInitialization(). This was already done by
you, but somehow I've lost the change when merging.
* Problem with incorrect class interfaces looks like introduced by my
quick replacement of awt classes. Going to investigate it.

Re: jchevm status?
Posted by Weldon Washburn <we...@gmail.com>.
Ivan,
It is great you are spending time on gnuclasspathadapter. As you have
discovered, there is a lot of work remaining to be done. It would be
really good if you can document the problems you had in when following
my directions.
How much time will you be able to work on gnuclasspathadapter? It
would be good to know so that we can figure out how to split the
project efficiently.
I gave up on specJVM98 for now because JCHEVM/SableVM eagerly resolves
classes. It keeps trying to pull in a bunch of specJVM98 AWT classes.
I tried hacking awt out of specJVM98 source code but it got way too
convoluted.
My current plan is to try to get Mauve's gnu/testlet/java/io/File test
to run. I hope to post mods to the native methods that are needed to
support gnu/testlet/java/io/File fairly soon.

I was also thinking of stealing pieces of DRLVM. I started this
project before DRLVM had been donated. Thus there were no pieces to
steal. But now things have changed. Thus time to reassess how to
move forward.

Interesting. Do you really mean, "helpfully"? Perhaps you mean, "hopefully"??

Re: jchevm status?
Posted by Ivan Volosyuk <iv...@gmail.com>.
Sure, if I have some outstanding results I'll share it. As for now...
It was quite challenging to run "hello world" using glue layer from Harmony-318.
Some changes was made to the classes layout, patched classes are a bit outdated.
I didn't found libvmi.so for jchevm, so I've taken modified version from drlvm.
There is no documentation about HyVMLSFunctionTable functions used by
harmony classlib, and it is used quite strange way. Helpfully, Weldon
has commented out its usage.
Hello world passed, by specjvm98 _200_check gives me:
java.lang.ClassFormatError: invalid interface access flags 0x0201
(for spec/harness/BenchmarkDone and spec/harness/SpecBenchmark)
The same is reproducible on jchevm with classpath.
When comment out this too stict check:
on classpath it works.
on harmony classes adapter there is a fatal error, which is strange:
spec.benchmarks._200_check.Main does not implement the SpecBenchmark interface
---------
Eclipse on jchevm with classpath throw following (didn't spent much
time investigating):

There's work going on making a "glue layer" between any GNU
Classpath-using VM and the Harmony Classlib.
It's not complete yet. Are you interested in helping? We're always
looking for new volunteers.

Yes, this is a bug I haven't been able to track down yet.
Any insights appreciated.
