MCH74A5 - The Java Virtual Machine has ended

What seemed a simple java from RPG solution prove to be my undoing.



The XALAN class is called from RPG to transform XML into HTML using a
custom XSL style-sheet.

This works fine until the style-sheet is found to contain some syntax
that causes XALAN to cough up an error which kills the JVM resulting in
MCH74A5.

The problem being that once MCH74A5 has occurred then any subsequent
attempts to use a JVM fail irrespective of which RPG program from which
they originate. So the job must be ended, in this case an HTTP server
thread.



I'm hoping that this situation does not occur in production since the
XSL style-sheet transformation will have been tested before promotion.



But it is a bit of a worry that java can potentially cause a whole job
be terminated instead of just the last execution stack.



Even so, it's still a bummer to have to end the HTTP job even during
development while iterating through style-sheet enhancements.

I don't seem to see any way around this.
