Since upgrading from Java 8 to Java 11, the Jackrabbit JCR setup in my project has stopped working; it's either not saving or loading the data correctly (haven't quite figured that out yet).
I just wanted to double check that Jackrabbit JCR does support Java 11?
Yes, it does, as it's easily discoverable on http://jackrabbit.apache.org/jcr/downloads.html and http://jackrabbit.apache.org/jcr/jackrabbit-roadmap.html.
What version do you use?
