These classes implement a cleanup-at-vm-exit mechanism, which uses `finalize` as the cleanup method. It is unclear if the classes that implement `FinalizableObject` can actually get cleaned up before VM exit through normal GC and execution of finalizers. Simply adding a Cleaner does not provide the cleanup-at-vm-exit functionality. You need to rename Finaliz* to Clean* and keep all these classes, as well as adding a Cleaner - which should be done as part of CleanableObject.
