RFR [13]: 8218618: Program fails when using JDK addressed by UNC path and using Security Manager

[Weijun Wang]

The fix looks fine to me.

However, is PolicyUtil::getInputStream correct? Will it cause any problem when a UNC path is used in -Djava.security.policy?

I've seen several code changes around UNC recently. Wonder if we've finally fix it and PolicyUtil::getInputStream can always call url.openStream() now. I've added core-libs-dev at o.j.n, maybe someone there can give a clear answer.

Thanks,
Max
