Even trying to ignore the JDK-Updates does not work, using the following
entries in /etc/pacman.conf:

IgnorePkg   = jdk9-openjdk jre9-openjdk jre9-openjdk-headless
openjdk9-doc openjdk9-src
IgnorePkg   = jdk10-openjdk jre10-openjdk jre10-openjdk-headless
openjdk10-doc openjdk10-src
IgnorePkg   = jdk11-openjdk jre11-openjdk jre11-openjdk-headless
openjdk11-doc openjdk11-src
IgnorePkg   = jdk17-openjdk jre17-openjdk jre17-openjdk-headless
openjdk17-doc openjdk17-src
IgnorePkg   = jdk20-openjdk jre20-openjdk jre20-openjdk-headless
openjdk20-doc openjdk20-src
IgnorePkg   = jdk21-openjdk jre21-openjdk jre21-openjdk-headless
openjdk21-doc openjdk21-src
IgnorePkg   = jdk22-openjdk jre22-openjdk jre22-openjdk-headless
openjdk22-doc openjdk22-src

Anything else I can do?
