Mircea Markus commented on ISPN-2321:
-------------------------------------

With 1PC transaction don't cache the prepares and also update txStores in the prepare instead of caching them till the commit.

> We noticed a memory leak in CacheStoreInterceptor where the "txStores" and "preparingTxs" maps get not cleaned up after a transaction is completed and org.infinispan.transaction.xa.GlobalTransaction objects accumulate in these maps.
> This occurs in connection with transactional caches with pessimistic locking.
> See attached test case.
