[8u40] request for review and approval to backport JDK-8062747: Compiler error when anonymous class uses method with parametrized exception

[Jan Lahoda]

Hello,

I'd like to ask for a review of a backport fix, and an approval to push 
it to jdk8u/jdk8u-dev, for the following bug:

Bug: https://bugs.openjdk.java.net/browse/JDK-8062747
jdk9 fix: http://hg.openjdk.java.net/jdk9/dev/langtools/rev/0b467b70ad82
jdk8u patch: http://cr.openjdk.java.net/~jlahoda/8062747-8/webrev.00/

The difference between the JDK9 and JDK8u fixes is that the JDK9 fix 
uses "WriteableScope" and "WriteableScope.create" while the JDK8u fix 
uses "Scope" and "new Scope" (respectively), because WriteableScope is 
only in JDK9.

Thanks,
    Jan
