This is in fact the documented behaviour for finder methods. The only method
which throws any exception when it can't find a match is findByPrimaryKey,
which throws a NoSuchEntityException (a subclass of FinderException).
Otherwise, CMP finders just return an empty collection. This is in the jboss
doco, but I can't tell you where, since I don't have web access right now.
What makes you think it should throw a FinderException?
