Please, add to the bug report the command line and machines you used to 
reproduce the problem.

Phil, the problem is triggered during special mode testing in JVM 
-XX:+CompileTheWorld. In this more JVM loads all classes in specified 
.jar file and compiles (JIT compilation) all methods in class. It is 
stress test for Hotspot JIT compilers. For such tests we don't set DISPLAY.
