OK, I reproduce the build issue with JDK 21.
As said, for me it's not a blocker as Karaf 4.4.x is supposed to be built
with JDK11.
JDK21 min version for build is planned for Karaf 4.5.x.

Just as a reminder (according to https://karaf.apache.org/download.html
):
Karaf 4.4.x is still built with JDK 11 (it supports JDK 17/21 at
runtime,
but the build is Java 11).

Hi,
I have an error when building from the source on dist but the dep is on
maven central.
Is there a min/max maven version?
I am using a jdk 21 and maven 3.9.12.
Any idea?
