> 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).
