[Jamvm-general] JSR 308: symbol JVM_GetClassTypeAnnotations not defined for JamVM + OpenJDK 8

[Xerxes R. <xe...@za...>]

Hi Robert

First big thank you! I have been browsing through the list of changes to get
JSR 292 working;
http://git.berlios.de/cgi-bin/cgit.cgi/jamvm/log/
well done!

Today i have tested to use the new JSR 292 fixed JamVM in combination with
the latest IcedTea 8 build-system and OpenJDK 8 b80. Using this initial
icedtea 8 patch:  http://old.nabble.com/file/p35228844/icedtea8-jamvm.patch
icedtea8-jamvm.patch  ...
I was about to celebrate and pop up the champagne or at least drink a large
cup of ice tea after a successful build of OpenJDK 8 using JamVM + JSR 292
celebrate... but instead I discovered this:

./java -verbose:jni -version
[Failed to open library
/home/xranby/icedtea-8-b80/openjdk.build/images/j2sdk-image/jre/lib/i386/libjava.so:

more information

Error: Could not create the Java Virtual Machine.

Apparently: OpenJDK 8 have quite recently merged in the new JSR 308 and this
require some new functionality inside the libjvm.so

This patch looks fine and can be committed for me.  Thanks for testing
JamVM on IcedTea 3.x! :-D

This doesn't look too bad for Rob to add.  It's just more classfile metadata
like the ones for the existing annotations.  Hopefully, GNU Classpath will be
able to use it eventually too.

You're right.  It's fairly trivial as in OpenJDK all parsing of the
annotation data is done in Java.  The VM just needs to attach the
bytes somehow to the annotated class, method or field without too much
overhead (remembering that most classes have no annotations).
Unfortunately how annotations wer stored in JamVM was pretty dreadful,
so I've spent the weekend re-working it!

Thanks,
Rob.

omewhere without too much overhead

Thanks for letting me know - I was still using a version of OpenJDK 8 from
the end of December - must remember to update more often!

Rob.

I've now pushed JSR 308 support in JamVM:

http://git.berlios.de/cgi-bin/cgit.cgi/jamvm/commit/?id=10b7c81c597809b2aaf28c8243453a21c33d4af3

This relies on improvements in storage of annotations here:

http://git.berlios.de/cgi-bin/cgit.cgi/jamvm/commit/?id=0330f06b5839f4d8c316b46d92de9396dd7e95ad

Unfortunately this isn't going to help much in testing JSR 292 with
IcedTea 3 (OpenJDK 8)!  With the lastest versions of OpenJDK 8, the
JSR 292 jtreg tests are currently crashing.  I've not had time to look
at all the crashes in detail, but the first appears to be related to
uses of interface default methods - another new feature of JDK 8.
It's likely that the JDK has been updated to use them - I'm hopeful
that nothing has changed in the JSR 292 internals.

I started looking at interface default methods last week, before
stopping work to do JSR 308.  From the looks of it, it can be handled
by some modifications to the existing code in JamVM for so-called
Miranda methods.  Hopefully, it'll only take a couple of days.

The new JSR 292 implementation in JDK 8 was backported to 7 updates (I
believe 7u14), so JamVMs JSR 292 implementation should work with it,
although I haven't had time to try it myself (yet).

Thanks,
Rob.

I have worked on a new icedtea 3 patch:
http://old.nabble.com/file/p35272149/icedtea-3-openjdk-8-b80-jamvm.patch
icedtea-3-openjdk-8-b80-jamvm.patch 

This time OpenJDK 8 gets built using the JamVM libjvm.so and yes i agree
something with "default methods" in OpenJDK 8 break the build, at least i
see a related missing JVM_IsVMGeneratedMethodIx method during linking:

Thank you Robert
This issue is fixed, libverify.so is now linked correctly.
http://git.berlios.de/cgi-bin/cgit.cgi/jamvm/commit/?id=2040912557d789b1867b612811d0ddcf21e9def5
