/**

 *    this method will return "java.lang.Object".
 *    For code generated by Java 1.5, this answer is
 *    sometimes wrong (e.g., if the "clone()" method is
 *    called on an array).  A better idea is to use
 *    the {@link #getReferenceType(ConstantPoolGen)} method, which correctly distinguishes
 *    between class types and array types.
