Re: JVM Loop (was JVM locks up)

Dieter,

I am very interested in your response. Can you provide more information?

I have a jar file that comes from NT (not sure exactly what JDK is used to
create it). This jar file has a class that goes into a tight loop when
running on the AS/400 (V4R5 and V5R1). This loop does not occur on other
platforms (NT and Unix). The BCI job cannot be cancelled, even by ENDJOBABN,
and I have to IPL to get rid of it.

Any information on how I could solve (or work around) this problem would be
appreciated. I am new to java and java on the AS/400. Do you think that if I
do a CRTJVAPGM on my jar file that it would help? If so, what optimization
level do you recommend?

Can your looping problem be recreated with a small piece of java code so
that it can be reported to IBM and hopefully a fix can be developed?

Thanks,
-Marty

Mario,

in which environment does this occur JIT or static compiled? We've had
a bug in V4R5 and V5R1 executing nested loops in the JIT environment,
but it worked with a static compile with CRTJVAPGM.
