I'd say in part this isn't all that much different than the problems one faces already with Maven Central. If you release your library compiled for release 11/12/13/14 (or 8 back in the day when it was new) then users of those dependencies will get broken, and you have to rerelease or find some other solution.

The Maven model/pom files have no means to express JVM version in their dependencies other than using a classifier. Or one could go, with tooling support the direction sbt in scala went with a version numbering scheme ontop of mavens that included the JDK.

Using a classifier might be the simplest means - such as `com.example.foolib-1.2-previewjdk14`.
