When running the middlegen ant task I get the following exception:

ClassNotFoundException: middlegen.DontCloseLog4JLogSystem

My issue is similar to the one described at
http://www.mail-archive.com/middlegen-user@lists.sourceforge.net/msg01880.html

Im on osx 10.4.2 and java 1.4.2_07.

Hibernate version:
I have tried both with 3.0.5 and 3.1 beta 1 with same result.

It seems like I solved this my removing some jar-files from my $ANT_HOME/lib directory.
