Hibernate Reverse Engineering wizard with MariaDB

(Sorry, couldn't find a good place for this query - perhaps there ought to be a folder "MariaDB and ORMs"?)

I'm trying to use the Hibernate Reverse Engineering wizard with MariaDB. It's just a very simple example, but I am stuck. I don't see any errors, but it doesn't work as described.

Here's what I've got so far:

• Windows 7 x64, Eclipse Juno, MariaDB v5.5.3, Hibernate v4.2.3
• I've got an example with Hibernate running using annotations and the same instance of MariaDB, no problem
• Now I want to create the classes from the tables, so I'm trying to use the reverse engineering wizard.
• I've set up a simple DB and a couple of tables
• I've set up a hibernate.cfg.xml file using the same values as my working annotation example
• Now I use the wizard (in Eclipse) to "New/Hibernate Reverse Engineering File (reveng.xml)"
  • First page ok, second page "Configure Table filters" is where I'm stuck
  • I select the correct Console configuration (generated as part of creating the config file) and then press the "Refresh" button
  • At this point I should see my two tables in the "Database schema:" column. But it's empty.
  • I briefly see "Pending..." - then nothing.
  • I can't see any errors.

So, how to move forwards? Can I turn on some logging? Where is the error? What logs to check?

The Eclipse console window shows a bunch of stuff, all info, no errors and the last three lines are like this:

• 2013-08-22 11:34:38,189 DEBUG Worker-33 org.hibernate.connection.DriverManagerConnectionProvider - opening new JDBC connection
• 2013-08-22 11:34:38,198 DEBUG Worker-33 org.hibernate.connection.DriverManagerConnectionProvider - created connection to: jdbc:mysql:localhost:3306/omthibernate, Isolation Level: 4
• 2013-08-22 11:34:38,199 INFO Worker-33 org.hibernate.connection.DriverManagerConnectionProvider - cleaning up connection pool: jdbc:mysql:localhost:3306/omthibernate

In case it helps, here is the hibernate config (I've tried a lot of variations):
