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 structural constraint as described in the Java Virtual Machine Specification,
60 * 2nd edition, 4.8.2, pages 137-139.
61 * Note that the notion of a "structural" constraint is somewhat misleading. Structural
62 * constraints are constraints on relationships between Java virtual machine instructions.
63 * These are the constraints where data-flow analysis is needed to verify if they hold.
64 * The data flow analysis of pass 3 is called pass 3b in JustIce.
