[8u] RFA (S) 8059677: Thread.getName() instantiates Strings

[Aleksey Shipilev]

Thank you, pushed to jdk8-dev:
  https://bugs.openjdk.java.net/browse/JDK-8148842
  http://hg.openjdk.java.net/jdk8u/jdk8u-dev/hotspot/rev/efe013052465
  http://hg.openjdk.java.net/jdk8u/jdk8u-dev/jdk/rev/2cdb8c0719ad

But, did I push it right? It got "Fix Versions: 8u82", while I expected
8u76. Have we forked 8u76 already?

Cheers,
-Aleksey
