Assigning default ENUM values results in non-compilable java code if java namespace is not defined

enum Color {
  BLACK = 5,
  WHITE = 6
}

struct Params {
  1: optional Color bColor = Color.BLACK;
}

  public Params() {
    this.bColor = .Color.BLACK;

  }

  @Override
  public void clear() {
    this.bColor = .Color.BLACK;

  }
