Crash with annotated nested types

[wmdietl]

Take:

import java.lang.annotation.ElementType;
import java.lang.annotation.Target;

@Target(ElementType.TYPE_USE)
@interface TA {}

class Crash {
  class Nested {
    class DoublyNested {}
  }

  void foo(Crash.@TA Nested.DoublyNested p) {}
}

Running error-prone on this results in a few warnings plus:

Crash.java:12: error: An unhandled exception was thrown by the Error Prone static analysis plugin.
  void foo(Crash.@TA Nested.DoublyNested p) {}
                           ^

I didn't find issues with ANNOTATED_TYPE in them. Sorry if this is a duplicate.
