Description Julian Honnen CLA 2021-07-27 06:04:28 EDT 
I have a class where no content assist is offered for return types. I managed to reduce it to the following:

public class ReturnType {

  public Stri/* Content assist here is empty */ test() {

  }

  public void trigger(RetentionPolicy p) {

    switch (p) {
      case RUNTIME:
        break;
      default:
    }

    Callable<Void> c = () -> null;
  }

}


Removing either the switch or the lamdba makes content assist work correctly.
The issue is present both in 4.19 and in Version: 2021-09 (4.21)

at least this one is not a regression ...

It's exactly the same as bug 576068, so a regression since either BETA_JAVA12 or 4.17, not exactly sure which.
