That is correct. In 1.1 that method was non-functional.

A handle is something that you can use when for one reason or another you
need to reference a database object, but you cannot keep a normal java
reference to a proxy. This can be the case in stateless (sessionless) web
based systems; the handle can be trivially encoded into a url.

> Don't getting all objects of a type is no good, though:-(

And what equivalent would you use to retrieve all instances of a class in
a standard jvm without a database? IMHO an ideal database is just a
logical extention of the jvm; one should be able to use just pure java to
find objects.
