> When the FileCache is enabled, a static resource might be serviced directly when the DefaultAsyncExecutor.preExecute() is called, the finsh operation will be initiated but another thread might also decide to finish the operation, hence a thread race when calling AsyncProtocolFilter. The side effect is the ProcessorTask.recycle() can be called more than once, which will cause the SelectionKey to becomes null and create the regression noted by Mark.
