Bug Description

I can reproduce a crashing JVM when developing Eclipse plug-ins.

I can't share the workspace / code, but in addition to the usual hs_err_pid*.log could share 1 GB core dump file if anybody is here to debug this further, and I'm willing to try fixes to confirm if it resolves the crash.

The Problematic frame: j com.odcgroup.* is proprietary code, but its standard Java without any native code in that portion. There is native code in Eclipse SWT for GTK of course, but I THINK (but am not sure) that's NOT what's causing this one (contrary to Bug 1055159 which is clearly in libgobject).

FYI, just in case this additional finding may be useful:

Downgrading from JDK v7 (7.0_07-b30) back to this does NOT help - same crash - I'll attach separate second hs_err_pid*.log:

java version "1.6.0_24"
OpenJDK Runtime Environment (IcedTea6 1.11.4) (6b24-1.11.4-1ubuntu0.12.04.1)
OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)

Just FTR: My "workaround" until this is gets fixed is (has to be) using IBM's v9 JVM (Java7) - it works very nicely (no crash) !!

I stand corrected - I get a similarly smelling crash even on IBM's v9 JVM!! Does this mean this is caused by code they share??

FYI, this may be useful, so far no crash (same reproducible procedure) with very latest Oracle JDK! So:

BAD / crash:

java version "1.7.0_07"
OpenJDK Runtime Environment (IcedTea7 2.3.2) (7u7-2.3.2a-0ubuntu0.12.04.1)
OpenJDK 64-Bit Server VM (build 23.2-b09, mixed mode)

java version "1.7.0"
Java(TM) SE Runtime Environment (build pxa6470sr2-20120901_01(SR2))
IBM J9 VM (build 2.6, JRE 1.7.0 Linux amd64-64 20120809_118929 (JIT enabled, AOT enabled)
J9VM - R26_Java726_SR2_20120809_0948_B118929
JIT - r11.b01_20120808_24925
GC - R26_Java726_SR2_20120809_0948_B118929
J9CL - 20120809_118929)
JCL - 20120831_02 based on Oracle 7u3-b05

GOOD / no crash (so far):

java version "1.7.0_07"
Java(TM) SE Runtime Environment (build 1.7.0_07-b10)
Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode)

this is likely an issue with the libswt-gtk binaries included in the eclipse build. please report the issue where you did download this copy of eclipse.

Changed in openjdk-7 (Ubuntu):

I humbly beg to differ - according to attached log, this one does NOT occur in the libswt-gtk (contrary to Bug 1055159 which clearly is). This is a JVM crash IN NON-NATIVE JAVA CODE, which should be reported upstream to OpenJDK? But based on finding in comment #6 the latest Oracle JDK already has this fixed - the point of this point would have been to get that (RT ...b10... VM build 23.3-b01) into an OpenJDK *.deb on your repos. Assuming such refreshes happen "by itself" regularly, there is indeed nothing left to do in this bug.
