RFR: 8148626: URI.toURL needs to use protocol Handler to parse file URIs

[joe darcy]

Hello,

The change looks okay in that the new code is limited to the jrt 
protocol. I assume the failing test

     java/net/URL/B5086147.java

passes again with this change.

If a fix for this issue is not pushed soon, I want to have the failing 
test problem listed 
(http://mail.openjdk.java.net/pipermail/core-libs-dev/2016-January/038459.html).

Thanks,

-Joe
