You specify librarys you need (and their versions) per plugin, and if there are conflicting plugins, OSGi will solve the issue using classloaders.[15:48:43] <cheeser> "module" not "plugin"[15:48:44] <surial> elmomalmo: YOu have to weigh the memory load of caching against the CPU load of recalculating.[15:48:59] <surial> er, yeah, module, not plugin.
