This is a really nice feature. We tried it and it worked well for annotating the free text. We also encountered the same memory issue you already noticed. I believe the Apache common pool is not working as expected. I used JCasPool instead, to replace ObjectPool jcasPool. It seems to work much better. Hope this information can help.

Ah, that's useful to know. Would you be able to submit a pull request?

Just made a pull request. This change solely focus on the GC issue I encountered.
According to UIMA development guideline, in order to make an application to be thread-safe, need to produce multithreadable AE. But it seems the memory usage will go up as well when I have multiple (3) AE, but I don't see GC problem.
