URL.java (getURLStreamHandler): Check if we have to use cache before trying to retrieve handler from cache.

2003-09-27  Michael Koch  <konqueror@gmx.de>

	* java/net/URL.java (getURLStreamHandler):
	Check if we have to use cache before trying to retrieve handler from
	cache. Rename facName to clsName to match classpath more. Reformated
	some little pieces.
