Browse source 
2000-04-08  Anthony Green  <green@redhat.com>

	* java/lang/natObject.cc (_Jv_MonitorEnter): Only perform null
	check when we have to.

	* gcj/array.h: Mark elements(JArray<T>& x) and elements(JArray<T>*
	x) as `inline'.

	* java/util/StringTokenizer.java: Minor optimization.  Eliminates
	one method call.

	* java/util/Vector.java (VectorEnumeration.nextElement): Manually
	inline hasMoreElements.
