Aaron,

It seems that when the JVM needs starts with the headless property, it must run some sort of PASE routine, which must initiate a startup for the PASE environment for the job.
This only became apparent later when users of a totally unrelated application within the same job began reporting a system error that PASE had already been loaded.
It was apparent that their existing production application had been designed to run a routine via QP2SHELL.
I believe I tested that this had nothing to do with the PDF class itself by simply invoking any java class with the JVM headless property set to true.
If the JVM was loaded within the job before the existing app was requested then the error would occur, thus breaking an existing production app.
A data queue solution resolved both this and the JVM load performance hit.

So true.  This would be much better if a data queue layer were put in front
of it and have it run in a single batch job on the AS400 (which might be
what I end up doing for my customer).

How does java.awt.headless affect anything other than the Java runtime?  I
don't know if I have run into the issue you are alluding to.
