[rules-users] Guvnor causes NoClassDefFoundError when using functions

Hello all, I have been using Guvnor to manage some rules in a prototype system that we are developing. If I login to Guvnor, make some changes, and rebuild the package, sometimes I will get the following error: java.lang.NoClassDefFoundError: tpn/CompareBetween I have a function defined that is "compareBetween" and the syntax and everything looks correct in the generated DRL file. Sometimes, I can rebuild the package (without making any changes) and the problem will go away? Has anyone seen anything like this before?
