Description
function FindProxyForURL(url,host) {
	{
		return "PROXY proxy1:8080";
	}
}	

Using the simple proxy.pac file above, I see the following behavior in Java 1.6.0_18-b07 on both Windows XP and 2000, Firefox 3.5.0 and ff 3.0.18 (but not in IE 8.0 or 6.0):
In the Java Control Panel, although the auto proxy config script was checked, the plugin used the manual proxy configuration (although it was grayed-out.)  

I understand if the plugin can't read the autoconfig script, the plugin default should be to use *DIRECT*! 

Note: If I intentionally fill in the script location incorrectly, I can see the same behavior with IE 6&8.
