21 * Instances of this class are thrown by BCEL's class file verifier "JustIce" when
22 * a class file to verify does not pass the verification pass 3 because of a violation
23 * of a structural constraint as described in the Java Virtual Machine Specification,
24 * 2nd edition, 4.8.2, pages 137-139.
25 * Note that the notion of a "structural" constraint is somewhat misleading. Structural
26 * constraints are constraints on relationships between Java virtual machine instructions.
27 * These are the constraints where data-flow analysis is needed to verify if they hold.
28 * The data flow analysis of pass 3 is called pass 3b in JustIce.
