	It reads a System property on startup which we modify in a static block in jcifs.Config:

	    static {
	        Properties sys = System.getProperties();
	        synchronized( sys ) { 
	            if( sys.getProperty( "java.version" ).startsWith( "1.1." )) {
	                System.err.println( "jCIFS requires Java 1.2 or above. You are running " +
	                            sys.getProperty( "java.version" ));
	            }
	            String pkgs = sys.getProperty( "java.protocol.handler.pkgs" );
	            if( pkgs == null ) {
	                pkgs = "jcifs";
	            } else {
	                pkgs += "|jcifs";
	            }
	            sys.put( "java.protocol.handler.pkgs", pkgs ); 
	        }

	Then in SmbFile we make sure this is executed before accessing java.net.URL with:

	Class.forName( "jcifs.Config" )

	Just as an experiment, can you try to put this above line somewhere and run it *before*
	trying to use jcifs classes and see if that makes a difference?
