Vladimir Blagojevic commented on ISPN-2138:
-------------------------------------------

Sandro, I believe your fix works but we can not change implementation of NonTransactionalInvocationContextContainer just like that. I'll ping the author of that code on your behalf. Would you please in the meantime provide your cache configuration and if possible smallest example app so we can reproduce the problem locally.
