javac is too late detecting invalid annotation usage

Test case:

class Test<@DA T> { }

@interface DA { }

javac rejects it, with
play/src/Test.java:1: error: annotation type not applicable to this kind of declaration
class Test<@DA T> { }
           ^
1 error


javadoc accepts it, and generates docs
