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

[Steve Sides]

Hi Werner,
  I was just running the test with the lates t-a build to update tests 
and came across a crash.
It's in type-annotations and not yet tl/langtools.

import java.lang.annotation.*;
import static java.lang.annotation.RetentionPolicy.*;
import static java.lang.annotation.ElementType.*;

class Test1<T> {
     Object mtest( Test1<T> t){ return null;  }
     public void test() {
         mtest( new Test1<T>() {
                 @A @B String odata1 = "test";
            });
    }
}

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