[armedbear-devel] integrating abcl into Protege

Actually, Pathnames of the form "jar:URL!/ENTRY" can now use an  
arbitrary URL as long as the java.net.URL constructor returns an  
instance we can use to get a URLConnection. There is a rather  
elaborate plugin mechanism to register additional protocols, which I'm  
guessing OSGi implements for bundle: but somehow returns something  
which behaves slightly different from the built-in file: and http:  
protocols that I tested with.
