> In xaHelper the method handleException returns nothing (void), but it always throws an
exception. Typically used inside a catch-block, this pattern confuses (static) code analyzers
and reduces code readability.
> In this case it is possible to make the method return SQLException and write "throw handleException(t)",
which makes it clear that the flow will stop if it reaches the catch block. Note that the
method may still throw a RuntimeException, which I will document in the method Javadoc.
> The latter pattern is other places in the Derby code base, but I haven't checked for
consistency. One specific case worth mentioning is the one in DRDAConnThread. This one is
different in that it only takes correct actions, but doesn't actually throw an exception since
we wan't the server thread to keep processing/executing after having cleaned up and informed
the client.
