Hi,

I had a similar problem and solved it by changing the data source 
implementation.

I found that my tests passed if I ran them against a MySQL database but failed 
against hsqldb. After some experimentation I found that the problem was the 
data source I was using. I switched to org.apache.commons.dbcp.BasicDataSource 
and it now works.

I hope this helps!

Cheers
