Re: [rules-dev] [rules-users] ClassNotFound on class defined in drl with 5.5.0.CR1

I just pushed the fix for the issue you found. Regards and thank you again for having pointed it out, Mario Hi All, As a first time GIT user... I think I have manager to "pull this off" and submitted a pull request for a test case in the drools-compiler project. This should add one file in src/test/ in the package org.drools.compiler.integration as I deemed that to be the most appropriate place.
