uima concept mapper : multi threading issue

[shreya <sh...@gmail.com>]

Hi,
I am using UIMA for annotating some documents using Concept Mapper. I have 
built the dictionaries and configured it to our requirements. It gives 
expected results in case of single threaded requests.
However in multithreaded environment, it gives exception in the concept 
mapper add on code, giving blank result for some documents.

Exception:
Caused by: 
org.apache.uima.analysis_engine.annotator.AnnotatorProcessException: Trying 
to access value of feature  as "uima.cas.FSArray", but range of feature is 
"uima.cas.FSArray".

Is concept mapper add on thread safe ?

I’m sorry, I didn’t take great pains to make ConceptMapper thread safe. I have many updates to the code that I have been terribly slow to get into the distribution, but I have not seen this particular issue. If you could send me more information, I would be glad to look further.
