--------------------------------------------------------------------
I'm a bit concerned because Java 21 will be out next month, and there still
doesn't seem to be a plan how to deal with this.
We had similar issues in the past in Jackrabbit (java.security.acl,
https://issues.apache.org/jira/browse/JCR-4246), so let me provide some ideas...
What we did back then:
- deprecate the problematic API, and add logging for cases when the problematic
API is still used
- add a replacement that will be compatible with future Java versions
For a transition period, we kept both, and increased the default logging level
for cases where the deprecated API was used.
