org.jboss.byteman.rule.exception.TypeWarningException
A sepcialization of TypeException which can be thrown during type checking to indicate that a rule has failed to type check for a legitimate reason. It indicates that rule execution should be inhibited even though the rule has already been injected.

                        Method method = nextClass.getMethod(triggerMethodName, paramTypes);

                            if (exceptionTypes[i].isAssignableFrom(type.getTargetClass())) {
                                throw new TypeWarningException("ThrowExpression.typeCheck : exception type declared by rule target method but not by trigger method "  + typeName + getPos());
