Hi Everyone,

I can reproduce the crash below with the latest class library and I
can also see the cause of it.

What happens is that the harmony launcher has been changed to close
the jvm library after it is done (by calling hysl_close_shared_library
(handle)). This causes our harmonyvm.dll to be unloaded along with all
of it's static data. The problem is that we used some static strings
in calls to hythread_global(), but when harmonyvm is unloaded, these
strings go away as well.

A couple of solutions:
1) Don't unload the library. It will go away when the process ends anyway. 2) We could allocate the strings on the heap instead of using static memory. 
3) Provide a way to remove a hythread_global during shutdown.

If you want a fast workaround, use 1) and just patch
classlib\trunk\modules\luni\src\main\native\launcher\shared\main.c so
it doesn't call hysl_close_shared_library.

I've got the below dump while trying to run HelloWorld on this new
combination (jRockitVM + fresh Harmony classlib) combination. It seems there were significant changes in classlib since r487452 this version 
of jRockit was tested with.
