> fastdoubleparser 1.0.0 includes a META-INF/versions/22 directory
> maven-shade-plugin does not support class version 66 (relates to classes built with JDK 22)
> I know Java 22 is still in early access mode but this still allows lib maintainers to include java 22 classes in their multi-release jars.
> Would it be possible to ignore the class version or code defensively so that maven-shade-plugin can workaround it when class version is a little ahead?
> To reproduce the issue, try to build https://github.com/FasterXML/jackson-core (2.17 branch, the default) but remove this line from the pom.xml:
> <exclude>META-INF/versions/22/**/*.*</exclude>
