Filed By : JCK Team
JDK : JDK1.5.0
JCK : JCK 6.0 Build B01
Platform[s] : Windows XP
JCK test owner : http://javaweb.sfbay/jct/sqe/JCK-tck/usr/owners.jto
Failing Test [s] : api/java/awt/Toolkit/CursorTests


Test source location:
=====================
api test source:
/java/re/jck/6.0/promoted/beta/b01/


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:
#
