[hibernate-dev] Building with debug/trace log level

Reviewing your stack trace, I can see that you're using debugf, which 
passes through to the logger.  If you have an error in your format then 
there is nothing which can be done about that by the logging framework. 
  You would get a similar error if you were using String.format() 
directly with an invalid format string, and with the same level of 
validation (which is to say, none at compile time).
