Hi Matthias, hi arm* porters

building openjdk-21 is currently still stuck on openjdk-21
build-depending on itself:

https://buildd.debian.org/status/package.php?p=openjdk-21

Dependency installability problem for openjdk-21 on armel:

openjdk-21 build-depends on:
- libcups2-dev:armel
libcups2-dev depends on:
- libcups2t64:armel (= 2.4.7-1.2)
openjdk-21 build-depends on:
- openjdk-21-jdk-headless:armel
openjdk-21-jdk-headless depends on:
- openjdk-21-jre-headless:armel (= 21.0.2+13-2)
openjdk-21-jre-headless depends on:
- libcups2:armel
libcups2t64 conflicts with:
- libcups2:armel (< 2.4.7-1.2)

Dependency installability problem for openjdk-21 on armhf:

openjdk-21 build-depends on:
- libcups2-dev:armhf
libcups2-dev depends on:
- libcups2t64:armhf (= 2.4.7-1.2)
openjdk-21 build-depends on:
- openjdk-21-jdk-headless:armhf
openjdk-21-jdk-headless depends on:
- openjdk-21-jre-headless:armhf (= 21.0.2+13-2)
openjdk-21-jre-headless depends on:
- libcups2:armhf
libcups2t64 conflicts with:
- libcups2:armhf (< 2.4.7-1.2)

Somebody did the work to provide boostrap builds of openjdk-17 on armel
and armhf. We need the same for openjdk-21.

Cheers
