[PATCH] Small fix for Jetty 4.2.14

[Dalibor Topic]

Hi,

attached is a small fix for Jetty 4.2.14 that is needed to get Jetty to 
work with Classpath's file URL Connection. Jetty otherwise breaks on 
startup and complains that webapps/templates can not be found, despite 
that it exists. Jetty wants to access the path of the file permission on 
a file URL connection to determine the existence of a file, apparently.

The fix overwrites getPermission the file URL connection to return a 
FilePermission with the file path and a read permission.

cheers,
