Log message:
2004-09-07 Hans Boehm <Hans.Boehm@hp.com>
* java/lang/natObject.cc (LOCK_LOG, LOG): Add debug tracing.
(Almost everywhere): add LOG calls, fix, add comments.
(_Jv_MonitorEnter): Replace masking of LOCKED bit with assertion.
Add explicit check for LOCKED bit in slow case (PR 16662).
(_Jv_MonitorExit): Add casts in debug-only code.
Always release LOCKED bit before throwing exception.
(_Jv_ObjectCheckMonitor): Lock may be held if lightweight lock
isn't. Handle easy cases without lock acquisition.
(Object::wait): Use NotifyAll for lock inflation.
