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).
