Ok, with a bit more research...

With the official Solaris releases:
jpda.jar, libjdwp.so, dt.jar and libdt_socket.so are all part of JDK 1.3,
but are _not_ part of JDK 1.2.2.  And, in particular, they are not part of
the JDK 1.2.2 source code we currently have access to under the SCSL.

Now, the Blackdown folk, who have access to the JDK 1.3 source code, have
obviously included these libraries and jars into the Linux JDK they have 
released.

I've just sucked down the JDK 1.3 Beta source which is available under
the SCSL, and (after a _very_ brief look) it appears as though it may
include the appropriate code for building the necessary thingies.  We might
be able to graft this code into the FreeBSD native JDK but I'll need to
have a better look at this when I have time to be sure.
