Use @Test annotation to test for exceptions being thrown

Browse Source 
Please note that this commit only uses the @Test annotation
where exceptions are thrown at the end of the test,
because otherwise the test would not be executed completely.

Examples for this are in DatabaseComponentImplTest where many exceptions
are thrown in close succession or in ConnectionRegistryImplTest where an
exception is thrown in the middle of the test.
