Patch: Class initialization fix

[Matt Welsh <mdw@cs.berkeley.edu>]

The enclosed patch fixes problems when multiple threads are blocked
waiting for a class initialization to be done by another thread;
notify() has been changed to notifyWait(). There may be other class
state transitions which require a patch of this sort.

1999-09-01  Matt Welsh <mdw@cs.berkeley.edu>

	* java/lang/natClass.cc: Fixed notification of threads
	  when class initialization is complete.
