Project Detroit resurrects an OpenJDK effort to run JavaScript and Python from Java via the javax.script API by shipping tiny bridge code rather than a full engine rewrite. It uses V8 bundled for JavaScript with a C++ header bridge, and CPython per-version adapters (3.12/3.13/3.14) exposed via Panama/Jextract for Python. Detroit surfaces as a separate Maven artifact (not in the JDK), source and repos are live, and internal tests report it already implements javax.script backend and works.
