Hi Matt, we could modify the build to generate distinguish packages for the various JAVA version (at least for the LTS supported versions, like Java 11 and Java 14).
The thing is that we added some Jenkins tasks for Java 11 and 14n, and MINA tests fail with those versions, so there are thing we need to investigate before cutting a new release. Not that it should forbid us to get those specific versions though, it's just that we need to get that fixed first. Regarding the build process, I can foresee the usage of profiles to get those specific packages cut. However, we need to find a way to have a common code base, with a way to make the extensions optional. That probably mean excluding some specific java file from being compiled in Java 8 - assuming we can limit the impact on just a few added files -. Or maybe a separate maven module ?
