Compiler support for private interface methods.

[Srikanth]

Hello !

The javac team is pleased to inform you that the compiler support for 
private methods in interfaces
has been released through here:

JBS: https://bugs.openjdk.java.net/browse/JDK-8071453,
HG: http://hg.openjdk.java.net/jdk9/dev/langtools/rev/592d64800143

into the JDK9 dev stream.

This is a special announcement to the core libs team so you can consider 
whether there are libraries
that could be retrofitted to use this feature - 
https://bugs.openjdk.java.net/browse/JDK-8074282 is
also in consideration - when this is completed, you will have 
suggestions from the compiler on where
such refactorings are possible.

We appreciate your testing and any feedback and defect reports.

Thanks!
Srikanth
