Failing Test [s]     : api/java/awt/Toolkit/CursorTests

Test source location: 
api test source: 

Problem description:
Tests may randomly crash due to memory access violation inside a native method.
It can be reproduced using the Reference Implementation for Windows.
Running the test under Reference Implementation for Windows many times, 
failure rate is about 15-20 crashes per 100 consecutive runs.

How to reproduce: 
Crash takes place not on every run.
Tests should be executed in standalone mode:

cd %JCK_HOME%\classes
%JAVA_HOME%\bin\java.exe javasoft/sqe/tests/api/java/awt/Toolkit/CursorTests -TestURL file://%JCK_HOME%/tests/api/java_awt/Toolkit

Test output: 
RI crashes with post-mortem message like this:
# An unexpected error has been detected by HotSpot Virtual Machine:
#  EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x7c9010f3, pid=204, tid=2436

We are planning to get rid of finilizers in 6.0 so this one will get fixed automatically.

The fix for finalizers will be in 6.0b51.  It can be back-ported.

the problem is not reproducible in 6.0, so I'm closing this CR "as not reproducible in 6.0"
