-------------------------------------

Hi Carsten,

I have run your unit test against 5.2.0.Beta5 and it passes now. It does fail on Beta4, so I think it's worth merging your unit test for regression.
Your suggestion regarding AbstractTxLockingInterceptor.waitForTransactionsToComplete() was implemented in ISPN-2410/ISPN-2472. I believe this fixes the issue and can be closed as duplicate of ISPN-2410. Could you please also try this and confirm? 

Thanks!

> I have a replicated cache with locking mode set to PESSIMISTIC on which I use explicit locking before putting some value.
> After nodes have left the cluster, this does not work anymore and I get TimeoutExceptions like:
