Re: JVM Loop (was JVM locks up)

[Dieter.Bender@xxxxxxxxxxx]

Marty,

our program did not loop, we've got a null pointer exception at a not
existing statement. The problem only occured in the JIT environment and
in the meantime we've got a ptf to fix it.
with the the static compile I would recommend the former default level
10, as with all compilers.
