We are seeing some strange behavior in 6.2.0, which might be related to TS-4387 and we did not see this in 6.1.x.
In the case of long running processing on a continuation we run into the problem that a TSContSchedule for this continuation will be waiting for the continuation to end. If I read https://issues.apache.org/jira/browse/TS-4387 it is expected that the mutex is checked on being present, but FORCE_SCOPED_MUTEX will also enter the mutex in the TSContschedule. This behavior negates https://issues.apache.org/jira/browse/TS-3569, relaxing mutex requirements. I wonder which is the desired behavior. Probably inbetween? Asserting the mutex, but not entering it?
