MySQL 5.0 and jdbc - unexpected end of input stream

[Robert Mazur]

MySQL 5.0 alpha (binary install) on
Solaris 9 -or- RedHat 8.0

mysql-connector-java-3.0.8-stable
-----------------------

Is there something different going on with JDBC and the alpha version
of MySQL 5.0? When trying to connect I am getting:

** BEGIN NESTED EXCEPTION **

java.io.IOException
MESSAGE: Unexpected end of input stream

The client machine trying to connect to the server *CAN* connect via
the mysql command line client (ie. is has permission to the servers).
I have tried connecting to version 5.0 installs on both Linux and
Solaris with the same result. If I point the driver back to a 3.23.57
install, it works fine as always.

Here is more of the error, and code to connect further below:
------------------------------
java.sql.SQLException: Communication link failure:
java.io.IOException, underlying cause: Unexpected end of input stream

** BEGIN NESTED EXCEPTION **

java.io.IOException
