Vladimir Beliaev commented on HARMONY-1756:
-------------------------------------------

I failed to reproduce this issue on Windows/IA32 (as was reported) on today version of DRLVM. 

Both old version (as Geir wrote) and new one are not reproducible:

For old version On Windows/IA32 with JAVA_HOME unset (from cygwin): 
- version: svn = r478828, (Nov 24 2006), Windows/ia32/msvc 1310, debug build
- command: ./working_vm/build/deploy/jre/bin/java \
                       -cp ".;working_vm/build/make/tmp/junit.jar" \
                       junit.textui.TestRunner Bug
- log: 
    .Check point
    PASSED
    Time: 0.01
    OK (1 test)

For new version On Windows/IA32 with JAVA_HOME unset (from cygwin): 
- version: svn = r478828, (Nov 24 2006), Windows/ia32/msvc 1310, debug build
- command: ./working_vm/build/deploy/jre/bin/java Jira1756
- log:
    Check point
    PASSED

Output is identical to RI 1.5 one.

So the issue is either not reproducible or more information required for reproduction. 

Thanks 
Vladimir
