Core review request for 6378701 "(enum) Unclear purpose of EnumConstantNotPresentException "

[Joseph D. Darcy]

Hello.

Please review the patch below is clarify the use of certain exception 
types to address bug 6378701 "(enum) Unclear purpose of 
EnumConstantNotPresentException."  Five exceptions/errors can be thrown 
by the methods of the AnnotatedElement interface; those methods are used 
to retrieve annotations reflectively.  I've added cross references 
between the AnnotatedElement intefaces and the throwables it may throw.

-Joe
