--------------------------------------

Hi. I just discovered that this is a blocker for REST server testing.

The problem is causing HTTP status 412 when putting data on existing entry in lots of operations in our performance tests.
The failing point there is the call to replace
https://github.com/infinispan/infinispan/blob/master/server/rest/src/main/scala/org/infinispan/rest/Server.scala#L185
that returns false and that causes HttpServletResponse.SC_PRECONDITION_FAILED (status 412)

This is a testcase I've created for the REST server:
https://github.com/mlinhard/infinispan/commit/42dc7788715f5bad000940f4eb2736cf50c38271

It seems to me that the root cause of this is the bug you're describing here, so I'm not creating a new bug ...

> The local data container does not have the entry yet so the ReplaceCommand fails. See BaseDistStateTransferConsistencyTest.testReplace() and BaseReplStateTransferConsistencyTest.testReplace().
