Hi all,
I’ve been trying to build a native executable with GraalVM and got stuck with
this exception when running the executable:
java.lang.RuntimeException: java.lang.ClassNotFoundException:

I found a ticket that probably relates to the issue
https://issues.apache.org/jira/browse/CALCITE-4539
<https://issues.apache.org/jira/browse/CALCITE-4539>
I also found that substrait.io <http://substrait.io/> (substrait-java) already
compiles Calcite dependency to a native executable. Right now, I’m confused, is
it possible to compile Calcite to a working native executable or not? It would
be great if somebody could give some insight on how to do that. I tried to
apply the substrait-java configs and used the GraalVM trace agent generated
configs too but I still get the above exception nonetheless.
Thanks
