Marshall Schor commented on UIMA-29:
------------------------------------

I recommend we fix this by updating the docbook and the java doc to say it's not allowed, and the workaround.

> (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.
> Follow up:
> Sender: cwiklik
> 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?
