Re: jchevm status?
Archie,
This test seems to pass ok, any way the problem in eclipse was fixed
by following change. (Sorry, do not have enough time to write the
test)

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.

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.
Do you have a simple test case? This one seems to work OK:

[jchevm] Re: jchevm status?
That's great news...
And given the increase of activity around jchevm, can we remember to
prefix the subject line with [jchevm]... (I don't recall who started
this thread... doesn't matter... just a reminder)
Ivan Volosyuk wrote:
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,

Re: jchevm status?
Weldon, 2006/5/15, Weldon Washburn [EMAIL PROTECTED]: 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. 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. 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 am not planing to do much work on it. May be I'll spent some time in weekend. 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.

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

Re: jchevm status?
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): ...

Ivan Volosyuk wrote: Sure, if I have some outstanding results I'll share it. As for now... 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. -Archie __ Archie Cobbs *CTO, Awarix* http://www.awarix.com - Terms of use : http://incubator.apache.org/harmony/mailing.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: jchevm status?
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.
