It can and that works too. That was one of the alternatives I had initially tried. I explain in this previous comment https://github.com/openjdk/jdk/pull/16805#issuecomment-1825194163 the reason why I thought sharing the ServiceLoader might be better. Do you think I should just use the local ServiceLoader approach instead?
