HttpPostEmitter.close will lead task to hang forever because of emittingThread quit. ### Affected Version 0.12.3 ### Description The task's jstack information as follows:  - We found `emittingThread ` quit in jstack, but it should't quit before main thread. - `concurrentBatch` will be set `null` when close, then `needsToShutdown` may be `true` due to `concurrentBatch.get()` and `emittingThread` exit normally. - So we should add lock in `concurrentBatch.get()`, such as ``` synchronized (startLock) { Object batch = concurrentBatch.get(); ....... } ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
