Hi all, I'm finally back, rechecking this issue: https://pharo.fogbugz.com/f/cases/7241/Object-name-should-best-be-removed I remade the Slice to load in latest Pharo5 with the new Spur changes, plus some fixes proposed by Nicolai. I can load the slice in a new image and everything looks ok. So far so good. Now, the monkey starts checking the Slice and somehow it cannot load the Slice due to "dependencies to some classes". Of course, the slice I submitted does not depend on the packages on the complaint, and locally it loads well. Moreover, I never had/worked with those classes, nor they were installed in my system. Even, I have a new machine which is clean so I cannot believe I have some interference due to some package cache... The message of the monkey is here: https://ci.inria.fr/pharo/job/Pharo-5.0-Issue-Validator/26128//artifact/vali... Did somebody find some similar problem or it is just me? I believe the problem is on the monkey side, but I have no clue... Maybe somebody has a better idea. Thanks! Guille
