So far I’ve been going thru add !sun.util…..  etc. to my config and seeing what shows up – but it’s looking pretty much what I expected – A LOT of internal web/network fundamentals ( sun.net.www.http etc. ) all of which I’m guessing are extended/implemented by the OpenJSSE library ( which was a backport/extraction from JDK 11 ) so it’s part of the core/low level stack of Java.

I don’t think this route will be of much use, but I suspect I may have better results including the base jar in the lib/boot folder, and my bundle merely instantiating the class.

Are some of those possibly something you could make optional?

Dealing with old jars compile chains can be really enlightening in osgi :)
