Use J2V8 to replace the current JavaScript engine Rhino

[seanccc]

ThingWorx uses Rhino as its JavaScript engine . But Rhino is too slow ,  comparing to V8 its 10 times slower ,  why not use J2V8 (the Java integration of V8) instead ?

Yes, this should definitely be done.

Hello! 

Thank you for your idea and feedback.

We understand that J2V8 is a dormant open-source project which is not a viable option. We plan to evaluate GraalVM as an updated JavaScript engine in the future for this use-case planned for CY 2024-25 timeframe.

Hope  GraalVM  + typescript + debug  are in the plan together : )
