Description

(Issue reported on SourceForge)
My problem occurs when I call process() twice on a
CollectionProcessingEngine. The call bombs out with a
next to useless thread exception.

SEVERE: java.lang.IllegalThreadStateException

The docs appear to suggest its fine to call process
more than once just not at the same time.

This is a known limitiation and perhaps not well
documented.

Can you explain the use case for calling process on the
same CPE more than once?

Workaround for this limitation is to create a new instance
of the CollectionProcessingEngine. Is this for now
acceptable?
