Galder Zamarreño commented on ISPN-2172:
----------------------------------------

I think I've found the problem: L1ManagerImpl will only invalidate those keys that have been requested by others nodes (via a get()). However, if a node receives data as part of rehashing and it does not belong to it, it'd be added to L1 but it won't be registered as requestor, hence it won't be invalidated when the remove happens.

> There appears to be an issue L1 and removals. 
> Seems like on removal, non-owners are not invalidated and data is left in memory.
> If using a Hot Rod server, it would appear as if the remote get operations don't return anything after removal is cos it goes to an owner node, where data is indeed removed.
> However, if you try to build a test case with embedded cache, it clearly shows that after removal, data is left in memory.
