Anonymous classes are not final according to reflection API

[Georgiy Rakov]

I've filed the issue JDK-8129576. 
<https://bugs.openjdk.java.net/browse/JDK-8129576>

There is following issue in JBS: JDK-4777101 
<https://bugs.openjdk.java.net/browse/JDK-4777101> which seems to relate 
to this one.

Thank you,
Georgiy.
