        // Expected behaviour
        assertThat(ex.getCause(), is(C24AggregatedMessageValidationException.class));
        C24AggregatedMessageValidationException vEx = (C24AggregatedMessageValidationException) ex.getCause();
        ListIterator<ValidationEvent> failures = vEx.getFailEvents();
        int failureCount = 0;
        while (failures.hasNext()) {
