Re: Kawa maven plugin

[Duncan Mak <duncanmak@gmail.com>]

Right after sending my mail, I was reminded of (module-compile-options
main: #t) and with a few changes, I was able to make mvn compile work.

https://github.com/duncanmak/kawa-javafx-graalvm/commit/f06d1d839aeb0a3243145fdea9b5107ddfc3e53d

The next thing I tried is to use GraalVM and see if I can generate a native
image, alas, it looks like it's not working yet.

it looks like there are methods that cannot be compiled into a native image
by GraalVM.

[Fri Nov 20 23:38:11 EST 2020][INFO] [SUB] Error:
com.oracle.graal.pointsto.constraints.UnsupportedFeatureException: Invoke
with MethodHandle argument could not be reduced to at most a single call or
single field access. The method handle must be a compile time constant,
e.g., be loaded from a `static final` field. Method that contains the
method handle invocation: gnu.expr.CompiledProc.init(boolean, MethodHandle,
Object, int)

[Fri Nov 20 23:38:11 EST 2020][INFO] [SUB] To enable method handles that do
not require LambdaForm interpretation (e.g. because of a call to
MethodHandle.bindTo()) or to diagnose the issue, you can add the option
--report-unsupported-elements-at-runtime. The error is then reported at run
time when the invoke is executed and the method handle has to be
interpreted.

[Fri Nov 20 23:38:11 EST 2020][INFO] [SUB] Trace:

I see that GraalVM does work for Clojure,
https://github.com/BrunoBonacci/graalvm-clojure, I wonder what's to be done
to Kawa to make it work here.
