the package java and try to open a Java GUI i get a crash (output see

-----------------
My environment seems to be ok, because i can start the Swing GUI
manually with tclsh8.0.
Has anybody an idea what to try, or where to debug?
Where can i set the debuglevel of the JVM throu TclBlend?
Has anybody running similar configuration where works fine??
Thanks for a hint,
Marcel
