See bug 6411919 for changes to  src/share/classes/com/sun/tools/javac/processing/JavacProcessingEnvironment.java
                                     

EVALUATION

I think two overloaded getElementsAnnotedWith method could be justified:

1) The existing one that takes TypeMirrors, which is the type of object passed into the Process method

2) A new method that also took Annotation.class arguments
                                     

EVALUATION

For some common usage patterns (at least I keep running into them), 
this method would be very useful indeed.
