Offhand, this looks like a bug, please raise a JIRA. You said: " We also have DocBasedVersionConstraintsProcessorFactory in our UpdateProcessorChain for optimistic Concurrency.”
Optimistic concurrency is automatically enofrced on the _version_ field. The intent of this processor factory is to allow you finer control over optimistic concurrency by explicitly defining/populating fields. I do wonder whether you need this factory at all. If the intent is that any document with the same <uniqueKey> is updated with optimistic concurrency, you don’t need it at all.
