Description

If ProcessSession.append() is called multiple times for a FlowFile and in one of the calls other than the first call, an Exception is thrown, the claimant count is decremented more than once. This can result in the content being deleted or archived too soon. Consequently, this could also result in a NullPointerException being thrown when attempting to write to the FlowFile.
