Andreas Haas 86a2720763 [test] Make assertThrowsEquals use assertSame
The typical use of assertThrowsEquals is to check that a specific
object is thrown. However, assertEquals only does a proper equality
check for primitive types, not for complex types. Using assertSame
does a reference equality check on objects, which is more what you
would expect from assertThrowsEquals. For exception kind testing,
assertThrowsEquals actually did not work correctly, assertThrows is
better for that case.
