RFR(S) 8028553: The JVM should not throw VerifyError when 'overriding' a static final method in a superclass

[harold seigel]

Hi,

Please review this straightforward backport of the small fix for bug 
8028553 to JDK-8u. The fix ensures that a final method is not static 
before issuing a VerifyError, if another method appears to override the 
final method.  The fix is the same for both JDK-9 and JDK-8u.

This fix was tested with the test in the bug report, the new test, the 
JCK lang and vm tests, defmeth tests, ute verify and quick tests, and 
the hotspot, java util, and java lang jtreg tests.
