[eclipselink-dev] UnitOfWorkConcurrentRevertTest using the same ClientSession in multiple threads

Hi all,


we have experienced problems with the UnitOfWorkConcurrentRevertTest on SAP HANA database. It runs often without problems, but occasionally it hangs until it times out, leaving locks on the database. I investigated the issue and found out that the test uses the same ClientSession concurrently from two threads, resulting in concurrent access of the same JDBC connection (which is something HANA is rather sensitive to).


Is the test using the same ClientSession on purpose, or is this rather a mistake? If it’s by mistake, I would fix the test and have the threads use different client session. Otherwise I would skip the test on the HANAPlatform.


Thanks and best regards,
