- One thread keeps failing with OptimisticLockException until exceeding max-retry.
Description
OptimisticLockRetryInterceptor has "retries = 3" by default. When it exceeds the max retry, it gives up with the WARN message "Retry failed after 4 attempts".
But actually, it retries only 2 times so the number of attempts is 3.
The last sleepTime (800 ms) is just a sleep time before throwing an Exception.
Attached a unit test for branch 6.5.x because JpaOptLockPersistentStatefulSessionTest in master doesn't seem to work now (DROOLS-1393).
