A few classes need to be modified: - jamvm (from README): "A number of classes are reference classes which must be modified for a particular VM. These are provided and built along with JamVM (see INSTALL). JamVM 1.3.0 works with Classpath version 0.14 (the latest development snapshot). It should also work with the latest version direct from CVS (but check the Classpath mailing lists for possible patches). Later snapshots of Classpath may also work, if no modifications have been made to the VM interface." - jikesRVM fetches classpath from cvs, and allows you to put your own copy instead, to build the boot image. In addition, it implements or modifies, glancing at cvs code, gnu.classpath.(VMStackWalker.java| VMSystemProperties.java) and a bunch of classes (VM) in java.(lang|io| net|util).VM* (including also Object, Thread, Throwable .ref.*, some .reflect. classes) - sableVM (1.11.3) bundles a version of classpath with it, numbered after the sableVM release. I'm not sure how modified it is WRT CVS classpath, but the claim is "SableVM Classpath is based on GNU Classpath 0.08 + further CVS changes" (INSTALL-DEVEL) - not sure about other VMs This is inconvenient for VM writers, as they must bundle or track the development of those classes in both libraries. I think that this is why there was a suggestion to isolate all references in a separate "deliverable" (be it package, jar, bundle, whatever), so that people working in different VMs can have independent versioning and API changes than the library as a whole. This will become specially handy as classpath grows, because the VM* part will be fairly stable, but changes as implementation gets better or new APIs (JSR) get approved will be big.
