The 1st arg to `assertEquals()` should be the actual value, the 2nd should be
the expected result. I guess you expect `instant1` to be the expected result.
(TestNG and JUnit have opposite conventions...)

TestNG supports a better way for expected exceptions, as an attribute of the
@Test annotation. Maybe it can be used here for the expected failing cases?
