GraalVM is the way to go for Javascript and other language support
because Nashhorn is removed in Java 15.
While <optional>true</optional> or <scope>provided</scope>, the project
does not sip it nor do depending on Jena libraries inherit through
dependency management.
The build does not require them for java8 or java11.
(You can remove the dependencies and it still builds).
At Java15, that should be a problem but our JDK15 (targetting Java8
bytecode) works. I don't know how that happens.
The jena-arq POM does causes graalVM to be pulled in to build.
It seems to me that the intention is that GraalVM is like the JDK - it
just "is" on the platform (more like <scope>provided</scope>). But that
isn't how things work - what ever I'd tried for "provided", graalvm is
downloaded into my local maven repo.
Is this a case for <scope>system</scope>?

While <optional>true</optional> or <scope>provided</scope>, so depending
in Jena libraries does not require GraalVM, the issue is that the build
uses these.
