[8u-dev] Request for approval for 8168774: Polymorhic signature method check crashes javac

[Maurizio Cimadamore]

Please approve.

Bug: https://bugs.openjdk.java.net/browse/JDK-8168774
JDK 9 changeset: http://hg.openjdk.java.net/jdk9/dev/langtools/rev/6a79477df95d
Backport review thread: http://mail.openjdk.java.net/pipermail/compiler-dev/2017-January/010633.html


The changes did not apply cleanly because of minor changes in JDK 9 (see link to backport review).

Cheers
Maurizio
