Hi Chris, I've done some testing with your new version of Lvg with cTAKES 2.5.
To work with cTAKES 2.5, I did need to downgrade the version of hsqldb.jar to work with cTAKES 2.5 to avoid getting the error "Data File size limit is reached opening file". My guess is that is related to the UMLS data file and not Lvg. Running multiple threads in my test environment, I did not see any bleeding of data between cTAKES threads. Bleeding of data between cTAKES threads is what had occurred in the un-patched version of LVG 2010.
