> Hibernate L2 cache stores value in wrong cache
> ----------------------------------------------
>
> Key: IGNITE-4760
> URL: https://issues.apache.org/jira/browse/IGNITE-4760
> Project: Ignite
> Issue Type: Bug
> Components: Hibernate L2 cache
> Reporter: Semen Boikov
> Assignee: Vadim Opolski
> Fix For: 2.0

> Issue is reported here:
> http://apache-ignite-developers.2346864.n4.nabble.com/issue-with-Hibernate-2L-cache-region-factory-ignite-1-8-td14912.html
> First it is necessary add JUnit test reproducing issue (see existing tests in
> IgniteHibernateTestSuite).
> Currently Hibernate access strategies track updates using thread locals, and
> it looks like updates for different caches can be mixed. I think per-cache
> thread local can fix issue for HibernateNonStrictAccessStrategy, but
> per-cache thread local can not be used for HibernateReadWriteAccessStrategy,
> since it is assumed that all updates should be part of the same cross-cache
> ignite transaction.
> So possible fix:
> - use per-cache thread local for HibernateNonStrictAccessStrategy (or somehow
> track target cache in HibernateNonStrictAccessStrategy)
> - use single thread local for HibernateReadWriteAccessStrategy
