"Restarting Java" and "Restarting QShell"

Ok.  So I was running into some Java issues running from QShell and in an
attempt to fix the problem I killed two jobs in subsystem QUSRWRK that
appeared to have something to do with Java and QShell (i.e. they had JVA and
QSH somewhere in their names).  Well, now running Java from QShell seems to
be even worse in that when I try to run a program it stalls and hangs after
it has loaded a number of jar class files.
 
So here is what I am wondering.  Is there a way to "Restart Java and QShell"
on the iSeries, or rather stop and start the necessary jobs that take care
of running these things?
 
I know I shouldn't have been messing with jobs I had no idea what they were
doing :-)
 
More specifically the problem I am running into deals with running the
following Java command and having it stop during the loading of the .jar
files classes:
 
 ===> java -Djava.version=1.4 -Djava.awt.headless=true -verbose -cp
