RFR: JDK-8227046: compiler implementation for sealed classes, JDK-8227047: Javadoc for sealed types and JDK-8227044: javax.lang.model for sealed classes

[Joe Darcy]

Hi Vicente,

In PrintingProcessor, I believe the printModifers method should remove 
"SEALED" from an enum, assuming the latest policy for enums discussed in 
the JLS is implemented (tl;dr -- all enums that cannot be implicitly 
final are implicitly sealed).

In test/langtools/tools/javac/processing/model/element/TestSealed.java, 
List<String> expected might be better constructor from a text block. 
Since SealedClassesProcessor extends JavacTestingAbstractProcessor, it 
doesn't need to have be annotated with @SupportedAnnotationTypes("*") or 
have a getSupportedSourceVersion method which returns latest since that 
is built-into the parent class.

Thanks,

-Joe
