Your finder signature must be either Collection or Enumeration (which is
only there for backward compatibility with ejb1.0).
You can return a vector, _but_ just because your finder returns a vector
doesn't mean your client will get a vector. Remember that the container
has some things to do after you return the keys, and it _won't_ return
the same collection you give it.
