  57.  * Instances of this class are thrown by BCEL's class file verifier "JustIce" when

  58.  * a class file to verify does not pass the verification pass 3 because of a violation

  59.  * of a constraint that is usually only verified at run-time (pass 4).

  60.  * The Java Virtual Machine Specification, 2nd edition, states that certain constraints

  61.  * are usually verified at run-time for performance reasons (the verification of those

  62.  * constraints requires loading in and recursively verifying referenced classes) that

  63.  * conceptually belong to pass 3; to be precise, that conceptually belong to the

  64.  * data flow analysis of pass 3 (called pass 3b in JustIce).

  65.  * These are the checks necessary for resolution: Compare pages 142-143 ("4.9.1 The

  66.  * Verification Process") and pages 50-51 ("2.17.3 Linking: Verification, Preparation,

  67.  * and Resolution") of the above mentioned book.

  68.  * <B>TODO: At this time, this class is not used in JustIce.</B>
