Hi, the Pharo Kernel job is buildable on CI server again. Patch is now directly in unload scripts, I opened an issue: http://code.google.com/p/pharo/issues/detail?id=4833 Reasons of the failing builds were: - FreeTypeFontProvider was not listed in classes that has unload method (the shrinking process firstly removes this methods to avoid unwelcome side effects while classes removing and does the cleanup manually) - ClassQueryTest was in System-Support category, not in some standalone tests package The job Pharo Kernel Tests still fails. It requires to add some Ring packages directly to the Pharo Kernel image. Cheers, -- Pavel
