<div style="font-size: 11pt;">I hereby propose the (re)creation of the Detroit Project, with myself as<br>
the Lead and the Compiler Group as the sponsoring Group.<br>
<br>
The Detroit Project was originally created in February 2018 [1], with<br>
the intent to develop an implementation of the JCP-standard javax.script<br>
API [2][3] based on the V8 JavaScript engine [4]. This would enable<br>
JavaScript to be used as an extension language for Java applications,<br>
and likewise Java libraries to be accessed from JavaScript applications.<br>
The Project never got off the ground, however, so it was dissolved in<br>
September 2024 [5].<br>
<br>
Here in February 2026, there is still interest in using Java and<br>
JavaScript together. With the rise of AI, moreover, there is also<br>
interest in accessing AI functionality written in Python from Java<br>
applications.<br>
<br>
Some colleagues and I have therefore revived the original prototype<br>
JavaScript script engine based on V8, and have also prototyped a Python<br>
script engine based on CPython [6]. Using widely-adopted JavaScript<br>
and Python implementations, rather than re-implementing JavaScript and<br>
Python from scratch, ensures both low long-term maintenance costs and<br>
compatibility for existing JavaScript and Python code.<br>
<br>
We would like to move these prototypes into a proper OpenJDK Project<br>
in order to accelerate development. We expect to leverage and push<br>
the boundaries of the FFM API [7], so this work will likely influence<br>
Project Panama. Over time, the Project may consider implementing<br>
script engines for additional languages.<br>
<br>
The initial Committers will be:<br>
<br>
Jim Laskey<br>
Sundararajan Athijegannathan<br>
Jorn Vernee<br>
Mikael Vidstedt<br>
Henry Jen<br>
Maurizio Cimadamore<br>
Alan Bateman<br>
Hannes Wallnöfer<br>
Jan Lahoda<br>
Jaikiran Pai<br>
<br>
Votes are due by midnight UTC on Wednesday, 11 March.<br>
<br>
Only current OpenJDK Members [8] are eligible to vote on this motion.<br>
Votes must be cast in the open on the discuss list. Replying to this<br>
