I am experiencing sporadic null pointer exceptions when running LSC. My tasks
are setup to sync between AD and an Oracle DB. The null pointer exception
seems to occur when running more than one thread.
If I execute it with:
bin/lsc -t1 -f etc/ -s AD-Accounts
The sync usually completes successfully. If I utilize more than one thread,
the sync process will, more often than not, fail.
bin/lsc -t10 -f etc/ -s AD-Accounts
