Hi all,

I was looking for a short test to reproduce the vm-crash when using 
ObjectAlignment=16 but found an other combination of options which 
result in a vm-crash ;-)

I have attached the java-source to this email.
Please let me know, if I should report this on an other way.


The startup command is:
$ java -Xmx1g -Xms1g -XX:+UseLargePages -XX:+UseG1GC 
-XX:G1HeapRegionSize=16M Test
