      Description



      Name: igT44549 Date: 02/10/99


      /*

      javac compiles the following illegal program:
      (The two Y constructors are mutually recursive.)

      */
      package test;
      public class X {
          public static void main(final String[] args) {
      new X ().new Y();
          }

          class Y {
      Y () {
      X.this.this(X.this);
      }

      Y (X x) {
      x.this();
      }
          }
      }

      ======================================================================

      It is hardly necessary to use such a complex example, e.g., using
      the qualified 'this()' notation. The following case also exhibits
      the bug:

          class Y {
      Y () {
      this(1);
      }

      Y (int x) {
      this();
      }
          }
