Description

In the following example (minimized based on an actual editing session), opening code completion with Ctrl+Space after "obj." causes an exception:

public class SomeClass {
  private void someMethod() {
    String obj = null;
    SomeClass2.SomeClass3 foozle = obj. // To trigger error, open code completion after "obj."
  }

  class SomeClass2<K> {
    class SomeClass3<E> {
    }
  }
}

The exception is as follows:
