Not able to run cTAKES UMLS in parallel

[Kalyani Unnikrishnan]

Hi,

I am trying to make cTAKES accessible by multiple programs in parallel. I was 
able to remove the error on umls.lck by setting PARAMS_ISOLATION to 
TRANSACTION_SERIALIZABLE. But I am still getting the following error when 
multiple programs are running the pipeline at the same time (it works fine if 
it is run in sequence).

Caused by: java.sql.SQLException: file input/output error:
