You might want to remove the boolean_exception() method from
the ControlFlowMethods class (or move it to the end of the
class). It instantiates a new Throwable Object which causes
a whole bunch of methods to be translated and executed. On
arm and alpha this lead to a crash while creating a new thread
(the deleteHelper of java.io.File). This happens because the
java.lang.Thread constructor tries to access the ThreadGroup
of the current Thread which isn't created by the jit_stub.
The attached patch was an attempt to fix this, but I still
got the crash on arm. However if you're able to run the tests
with this patch, it's more likely to be a bug in the arm
jitter.

Helmer
