CascadingValueExtactorResolutionAlgorithmTest#parallelValueExtractorDefinitionsCausesException() expects an exception, but a correct implementation of the spec will not raise an exception in this case actually.

The exception is expected based on the assumption that two value extractors are type-compliant and container-element-compliant with the the first container element of IWrapper212<@Valid Bean21, @Valid Bean22> wrapper. While two of the value extractors registered in the test are type-compliant, only one of them is container-element-compliant. The fix is to change the type of wrapper into IWrapper21, in which case indeed two extractors are type-compliant and container-element-compliant and an exception must be raised.
