1. Create two cache managers.
2. Establish a cluster between them.
3. Create an invalidating (sync) cache on each node.
4. Configure a shared cache store.
5. Put entry on node 1.
6. Try to remove the entry on node 2.

See the attached Java test.

A work around was found by first doing a `get` to retrieve the value before calling `remove` to delete it.

A work around was found by first doing a `get` to retrieve the value before calling `remove` to delete it.

The cache `remove` method occasionally fails to return the removed value, and returns `null`.

Observed in two node setup in invalidation mode, with a configured cache store (Redis).

Tests reveal that about 40% of the times the method returns `null`, the remaining 60% the removed value is correctly returned.
