Nelson, this error:
"The system tried to return a common analysis structure to the pool from
which it was not checked out."
I think this is caused if you try to release a CAS that has been previously
released. Sure you
are not trying to release it twice? I think releasing an input CAS in AE
code is not a good idea. I am assuming
you have an asynchronous aggregate (queue in front of each AE). In such
deployments, the UIMA-AS is
responsible for releasing a CAS once it reaches a Final state. Within a
synchronous aggregate I am not sure
if you are allowed to release a CAS in your code. Perhaps others can chime
in. Can you confirm which
deployment you chose for this aggregate (synch or asynch)
