Hi,
The current version of test is not very clean and it works only because withKeepBinary() is a noop. The correct version would be to use plain cache for non-binary-object entry processor and use withKeepBinary for binary-object entry processor. You can see that EntryProcessor creation is encapsulated in a separate method testClosure() which is overridden in test inheritors. The same thing should be done for the cache.
