GraalVM is very interesting, but one big worry about integrating an Oracle product into Ignition is long-term licensing. If GraalVM suddenly becomes a commercial project, but is deeply entangled into our system, we're "on the hook" to pay for it, with few other options.
Suffice to say that we're not pretending Jython is the forever solution for Ignition scripting - but we're also not convinced by any of the alternative solutions we've encountered yet.
