Due to lack of available time maintaining SSVM and its per-version backend for each new JDK release we will be migrating to a system similar to SSVM, but not as crazy accurate. This will allow us to have the same API capabilities we want in Recaf but not have to worry about updating SSVM internals when hotspot backend changes occur each release. Maintaining SSVM is just not long-term sustainable with just hobby time. Its an amazing tool/library but is sadly something we'll need to step away from.
