AssertionError at com.sun.tools.javac.code.Type$AnnotatedType.<init>

[Steve Sides]

The test case is a little simpler even. The AssertionError occurs just 
using @A.
class Test1<T> {
     Object mtest( Test1<T> t){ return null;  }
     public void test() {
         mtest( new Test1<T>() {
                 @A String odata1 = "test";
            });
    }
}

@Target({TYPE_USE,FIELD})  @interface A { }
