FULL PRODUCT VERSION :


A DESCRIPTION OF THE PROBLEM :
It is possible to annotate the outer type of a receiver type even if the inner type is not parameterized.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile the attached code and look into the class file where the outer type is treated like a owner type of a parameterized type.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
javac emitts a compiler error.
ACTUAL -
javac writes the type annotation into the class file.

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
class Foo {
  class Bar {
    void qux(@TypeAnnotation Foo.@TypeAnnotation Bar this) { } // Foo is treated as owner type.
  }
}

@Target(ElementType.TYPE_USE)
@Retention(RetentionPolicy.RUNTIME)
@interface TypeAnnotation { }
