RE: Java and cleanup from exception

["Dennis Lovelady" <iseries@xxxxxxxxxxxx>]

... same question, different environment.  Once a java routine blows up in
the batch job, you'll have the same issue but at higher cost.  What do you
do about that? 

But it sounds like you are using embedded java; you're just not using it
interactively.  Else why are you starting JVM at all?
