I could be mistaken but I think these kinds of issues (it occurred with 
exec-shield in the past - see bug 5099186) are why the Java launcher 
creates the JVM in a new thread (and why we recommend custom launchers 
do the same). That ways any OS machinations with the initial thread's 
stack don't impact on the JVM's stack management.
