Hi, Jeff

First, could you show what java versions you tried (java -version)? And 
what OS you are using?

Second, could you try to run with -Xint? It will run in Interpreter mode 
only without JIT compilation.

Third, run only Client (-client) or Server (-server) VM. It will use 
different JIT compilers.
Note, that there is no Client 64bit VM. If you have latest jdk7update 
(7u10 or 7u12) or jdk8 you can specify next flags to use only Client's 
JIT compiler: -XX:+TieredCompilation -XX:TieredStopAtLevel=1.

Regards,
Vladimir
