    020/**
    021 * Instances of this class are thrown by BCEL's class file verifier "JustIce" when
    022 * a class file to verify does not pass the verification pass 3 because of a violation
    023 * of a constraint that is usually only verified at run-time (pass 4).
    024 * The Java Virtual Machine Specification, 2nd edition, states that certain constraints
    025 * are usually verified at run-time for performance reasons (the verification of those
    026 * constraints requires loading in and recursively verifying referenced classes) that
    027 * conceptually belong to pass 3; to be precise, that conceptually belong to the
    028 * data flow analysis of pass 3 (called pass 3b in JustIce).
    029 * These are the checks necessary for resolution: Compare pages 142-143 ("4.9.1 The
    030 * Verification Process") and pages 50-51 ("2.17.3 Linking: Verification, Preparation,
    031 * and Resolution") of the above mentioned book.
    032 * <B>TODO: At this time, this class is not used in JustIce.</B>
