Hi,
I tried to profile a Grails application. However when I try to run the
application in profiling mode I am getting the exception below. Grails
uses commons-logging and this exception looks like a classloader issue
between some TPTP components and grails. The FAQ of commons-logging also
lists such an exception
http://commons.apache.org/logging/commons-logging-1.1/troubl eshooting.html#The_Incompatible_LogFactory_Issue
and provides a workaround, however it does not seem to work.

Any thoughts are appreciated.

Thanks,
Seb
