      public abstract class VerifierConstraintViolatedException
      extends RuntimeException

  Instances of this class are thrown by BCEL's class file verifier "JustIce" whenever verification proves that some constraint of a class file (as stated in the Java Virtual Machine Specification, Edition 2) is violated. This is roughly equivalent to the VerifyError the JVM-internal verifiers throw.

                                    String post)

    - #### getMessage

          public String getMessage()

      Returns the error message string of this VerifierConstraintViolatedException object.
      Overrides:
        `getMessage` in class `Throwable`
      Returns:
        the error message string of this VerifierConstraintViolatedException.
