Description
I performed a search on yahoo for an area school:
        walnut grove pleasanton
I clicked on the link for "Welcome to the Walnut Grove Web", which ended up with the URL:
	http://www.pleasanton.k12.ca.us/walnut%5Fgrove/
This page has 2 applets on it, one of which failed to load on mustang (b34) and both of which failed to load on 5.0_01.

When I changed the URL to use an underscore instead:
	http://www.pleasanton.k12.ca.us/walnut_grove/
the applets loaded and ran fine (on both 5.0_01 and mustang b34).

Note that a google search uses the correct (underscored) link, so to duplicate this use Yahoo instead.

it seems that ascii substitution is common in emails and web, so plugin ought to handle URLs which contain such characters.

Here is the out put in the java console after the applet failed on mustang (note that some of this output is there even on the working version, but the stack traces are only there when it fails):

EVALUATION Using b54 this seems to be fixed. The first of the two applets is loading and the URL being presented in the Console is correct. It is a little unclear from the description what the problem is, "Here is the out put in the java console after the applet failed on mustang (note that some of this output is there even on the working version, but the stack traces are only there when it fails)". Maybe the submitter could verify?
