JDK-8057919 Class.getSimpleName() should work for non-JLS compliant class names

[Vladimir Ivanov]

John,

But the method Class.isAnonymousClass does not make a distinction between those two cases, which might sometimes lead to confusion.  I would view this as a bug in Class.isAnonymousClass.
For non-top level classes, Class.getSimpleName calls 
Class.getSimpleBinaryName which converts null to empty string, assuming 
it's an anonymous class. So, callers should not see null values.

Best regards,
