So a developer that wants to build a Java app needs to have a static library version of the entire JDK to link with into a single executable Java launcher. So in this perspective, the entire use of dlopen in a static build smells funny, and might be just a left-over from static build being more of a hack than a properly supported build option.

I’m glad to see this gone. Looks good!
