Yes, hopefully Dennis' suggestion will work.

It does look like whatever environment this code is running in, it is
using a rather old version of commons-logging. The reported exception
only occurs in commons-logging 1.0.x. Version 1.1 of commons-logging was
released in May 2006 and 1.1.1 was released in Nov 2007, and neither of
these should ever throw an exception (though you might not get any
logging in this case, as there is clearly something weird going on with
classloader hierarchies).

Regards, Simon
