During incubation, this dependency was raised as an issue.  Generally,
there are 2 ways to deal with Category X dependencies within an ASF
project:

1) Make it an optional part of the software.  This is what we do with
the nonoss build target, but won't work for the mysql-connector.

2) Make it a "system dependency" that is expected to be installed on the
system prior to our software.

mysql-connector-java (and the python equiv) were supposed to be handled
using option 2 (system dependency).  

Currently, our RPM packaging depends on the relevant RPM to pull this in
as a system dependency.  I can't tell with the DEBs, but that would need
to be reviewed.

The problem is that our maven poms pull down the jar automatically right
now.  This is the blocker for us.  I'm certainly not a lawyer, but my
understanding of ASF policy is that we need to make some changes before
making another release.

So, there appear to be three things that have to happen:

1) Confirm that the mysql-connector-java is a system dependency in the
DEB packaging.

2) Ensure that a "normal build" of the project using mvn does not
automatically download the mysql-connector-java jar files.

3) Retest the project to ensure that the above changes work.

Then we can re-spin an RC.
