/**
* Returns an AssertionError that describes the fact that the arguments of an invocation are different.

* it returns a class that extends it. Otherwise, if {@link junit.framework.ComparisonFailure} is on the
* class path (shipped with JUnit 3 and 4), it will return a class that extends that. This provides
* better IDE support as the comparison result can be opened in a visual diff. If neither are available,
* it returns an instance of
