JDK-8019345 (java.net.URI should be updated for RFC 3986): duplicate of JDK-6791060?

[Radov, Nicholas O]

It looks like issue JDK-8019345 < https://bugs.openjdk.java.net/browse/JDK-8019345> is a duplicate of issue JDK-6791060 <https://bugs.openjdk.java.net/browse/JDK-6791060>. Should one of those be closed?

Regarding the comment on JDK-8019345 about how the implementation differs from that required by RFC 3986, I am aware of two minor differences.
1. They added the IPvFuture rule. So a URI like "http://[v0.0]" should be valid but currently it fails.
2. They added the path-empty rule. So a URI like "foo:" should be valid but currently it fails.

Would someone be willing to update the issue with that additional information? I don't have an official contributor account so I can't add comments myself.
