Thread interruption

Hello all,
        I don't generally like my interface programs to
monitor files or data areas to determine when to shut
themselves down; I prefer to have them capable of
determining when the operator has issued ENDJOB,
ENDSBS, or PWRDWNSYS.  This prevents constant needless
I/O to some other control structure.
        I'm trying to find a way to gracefully end one of my
Java classes through the ENDJOB system command, in an
equivalent fashion to the RPG SHUTDN op-code.  Does
anyone have a method they would recommend?  I'm toying
with Thread.isInterrupted(), but I don't want to have
to check.  I prefer, if possible, to just catch an
InterruptedException or some similar mechanism because
the thread is usually in an indefinite wait on a data
queue (-1 timeout).  At this point, I've just
experimented with ending the job *CNTRLD from an
external (interactive) job and for some reason an
exception never gets issued.

        Any ideas would be greatly appreciated.  If I can get
this thing working the way I'd like, we'll have a lot
better chance at getting our shop migrated more
towards the Java world.

Thanks,
