> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Reporter: Mark Payne
> Assignee: Joseph Witt
> Priority: Blocker
> Labels: releasenotes
> Fix For: 1.0.0, 1.0.0-Beta
>
>
> 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.
