> regression in test from https://issues.apache.org/jira/browse/AMQ-2413
> required some investigation. Symptom was missing messages, turned out to be
> in the middle of the sequence. Issue with the priority kahadb cursors and
> setbatch. Set batch is invoked when the cursor memory is exhausted such that
> replay from the store can start at the correct point. If a call to setBatch
> was followed by a call to recover when there was still no memory space
> available, the cursor could skip the next pending message.
