JD-GUI can't decomplile jar from the network

[Bennyz1]

When opening the JD-GUI with jar which located on the network (without map drive)
e.g.
\machine\folder\test.jar
(using double-click on the jar or dragging jar into the JD-GUI)
then, the JD-GUI failed to show the decomplied classes.
this issue began since version 1.4.2 (it working ok with version 1.4.1)
