Hi,
In the current API we have a number of methods that return null, and so
the client has to do null checks before continuing. One example would be
descriptor access methods in the Qi4j API class. Same with
currentUnitOfWork().
I suggest that all of these are changed to throw
IllegalArgumentException or IllegalStateException (according to what
makes sense) instead, so that client code can rely on objects being
returned correctly in the "normal case".
WDYT?
