[11u] RFR 8216401: Allow "file:" URLs in Class-Path of local JARs

[Zhengyu Gu]

I would like to backport this patch to 11u, as it appears to be on 
Oracle's backport list.

The patch does not apply cleanly. The fix itself applies cleanly, but 
included test does not, apparently due to test infrastructure changes.
