Graham Triggs updated COCOON-2303:
----------------------------------
Attachment: sitemap.diff
> ThreadLocal in Sitemap EnvironmentHelper leaks on application undeployment
> --------------------------------------------------------------------------
>
> Key: COCOON-2303
> URL: https://issues.apache.org/jira/browse/COCOON-2303
> Project: Cocoon
> Issue Type: Bug
> Components: - Components: Sitemap
> Affects Versions: 2.2
> Reporter: Graham Triggs
> Attachments: sitemap.diff
>
>
> In sitemap-impl, there is a ThreadLocal that is used to store the
> EnvironmentStack. In the call to leaveProcessor, it pops an EnvironmentInfo
> off the stack. However, it doesn't clear the ThreadLocal when the stack is
> emptied. As such, there is a reference left over that can't be cleared
> normally when the application is undeployed.
> Patch clears the environmentStack ThreadLocal when the stack is empty (it
> will get recreated anyway in the enterProcessor if it's required later).
