Only for the javascript language (using Java 8 Nashorn, now deprecated

And those 3 test failures are really, really difficult to fix, because
of limitations/quirks in the Nashorn engine itself.
Could you please provide more information on this? Which tests are failing, and
what are the limitations and quirks of Nashorn that cause this?
Sure.
Regarding 'quirks': see issue SCXML-273 [1] which concerns the problem
that the Nashorn engine by default doesn't fail on referencing a missing
property. Which is tested by W3C IRP test 307.
Regarding limitations: there are two W3C IRP ecma test, 557 and 561,
which make use of XML DOM APIs in a condition, like:
cond="var1.getElementsByTagName('book')[0].getAttribute('title') ==
'title1'"
However Nashorn doesn't provide default/native XML DOM support, and
adding that would be (at least from my perspective) quite an effort, if
even properly doable.
That doesn't feel like worth the effort, with little added value/ROI.

Thank you,
