As the function triggers an explicit conversion, I’d like to inform
the caller that no conversion is possible (at least for now; we may
find other Java types that could be converted). I’ll certainly need to
add that in the documentation.

I’m still not sure if I will keep the recursive conversion (maybe that
should be controlled via an additional argument). For maps, it’s
certainly helpful.

Great, thanks.

Trying to use convert:from-java on a list of a custom Java object, I get:

[convert:java] Java object cannot be converted: "Word(text=test,
normalized=test)".

It should just marshal the Java object like is done with the Java interop
in this case.

My initial testing on other cases (set-to-sequence) indicate that it is
slightly faster than the XQuery code I had -- I haven't measured them in
isolation, just on a test example I have.

Kind regards,
Reece
