Re: EXCEPTION_ACCESS_VIOLATION since 1.1.3

I’m still experiencing the problem after all. JRuby 1.1.3 does give me
the EXCEPTION_ACCESS_VIOLATION as I described in the first post, even
after
removing json-jruby-1.1.2-universal-java-1.6. No problems with JRuby
1.1.2.

I was using json-jruby-1.1.2-universal-java-1.6. Removing it solved the
problem. Excuse me for the noise.

Hi,

The update to 1.1.3 breaks my application:

An unexpected error has been detected by Java Runtime Environment:

EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x6d8a1392, pid=5132,

tid=5492

Java VM: Java HotSpot™ Client VM (10.0-b23 mixed mode, sharing

windows-x86)

Problematic frame:

V [jvm.dll+0x31392]

and I see this is in hs_err_pid5132:

Current CompileTask:
C1:2867
!
ruby.jit.ruby.C_3a_.jruby_minus_1_dot_1_dot_3.lib.ruby.$1_dot_8.rexml.parsers.streamparser.parse30311837_10994782.rescue_1$RUBY$rescue(Lorg/jruby/runtime/ThreadContext;Lorg/jruby/runtime/builtin/IRubyObject;Lorg/jruby/runtime/Block;)Lorg/jruby/runtime/builtin/IRubyObject;

Java version is 1.6.0 update 7 on Vista x86. This problem doesn’t occur
with 1.1.2 or older releases. Any suggestions?

Thanks!

Very interesting! It looks like we can narrow this down to a specific
method in rexml that’s blowing up. Two things you should do:

  1. File a bug for this with all information you have.
  2. Specify jruby.jit.exclude=parse and see if you can reproduce it.

It shouldn’t be hard to hunt down. Ultimately it’s going to be a bug in
the JVM…no piece of bytecode should ever be able to crash the
JVM…but if we can reproduce it here we’ll handle talking to the
HotSpot engineers and finding a workaround in the compiler.

Thanks for the report!
