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