Subject: re PR libgcj/22211 ([4.0 only] Thread.interrupt sometimes causes
 abort if thread is already dead)

	PR libgcj/22211:
	* testsuite/libjava.lang/pr22211.java: New file.
	* java/lang/natThread.cc (finish_): Synchronize when updating
	alive_flag.
	(_Jv_AttachCurrentThread): Likewise.
	(interrupt): Only call _Jv_ThreadInterrupt if thread is alive.
	* java/lang/Thread.java (isAlive): Now synchronized.
