[Mulgara-dev] Fw: URI escaped things don't work...

[William Mills]

The following patch to the trunk appears to resolve the URI escaping problem.

I don't have the same version of the program that you do, but I can  
see that it's just re-throwing a URISyntaxException.  Evidently the  
parser is passing the characters through decoded.  I'd rather not  
stuff with the parser, but if you're not afraid of a recompile, do you  
want to go to the toURI method and try running the string through  
URLEncoder?

Regards,
Paul
