    20   * Instances of this class are thrown by BCEL's class file verifier "JustIce" when
    21   * a class file to verify does not pass the verification pass 3 because of a violation
    22   * of a constraint that is usually only verified at run-time (pass 4).
    23   * The Java Virtual Machine Specification, 2nd edition, states that certain constraints
    24   * are usually verified at run-time for performance reasons (the verification of those
    25   * constraints requires loading in and recursively verifying referenced classes) that
    26   * conceptually belong to pass 3; to be precise, that conceptually belong to the
    27   * data flow analysis of pass 3 (called pass 3b in JustIce).
    28   * These are the checks necessary for resolution: Compare pages 142-143 ("4.9.1 The
    29   * Verification Process") and pages 50-51 ("2.17.3 Linking: Verification, Preparation,
    30   * and Resolution") of the above mentioned book.
    31   * <B>TODO: At this time, this class is not used in JustIce.</B>
