Section 8.6.5 says that it is a compile time error for a constructor
to directly or indirectly invoke itself through a series of one or
more explicit constructor invocations involving "this". Javac is
in violation of this part of the specification.

Adapted from Modena test n0865201:

class X {
 X(int j) {
    this();
  }
 X() {
   this(10);
  }
}
