If you try to compile the following program, javac goes into an infinite loop.

public class test {

  public static class Inner {

    private int local1;

    test local2;

    public static final int local3 = 0;

    public void local4() {
      local2.local5();
    }

  }

  /* Making local5 public makes the problem (of javac looping) go away */

  private void local5() { }

  void local6() {
    Inner local7 = null;
    int x = 0;
    byte b = 2;
    byte z = (x == 0) ? Inner.local3 : b;
    x = local7.local1 + t1.f(0, x);
  }

}

class t1 {

  static int f(int x, int y) { return x + y; }

}


If you make a the specified field public, the compilation terminates.
