Having a quick look at the build log of collectd for '5.7.2-2ubuntu1.1'. Collectd has been build on top of openjdk-11-* found in bionic-proposed '11.0.2+9-3ubuntu1~18.04.*'
# Build Log Link: https://launchpadlibrarian.net/416916001/buildlog_ubuntu-bionic-amd64.collectd_5.7.2-2ubuntu1.1_BUILDING.txt.gz .....

Since then a few iterations has been made most likely due to regressions: $ rmadison openjdk-11-jdk | grep -i bionic openjdk-11-jdk | 10.0.1+10-3ubuntu1 | bionic openjdk-11-jdk | 10.0.2+13-1ubuntu0.18.04.4 | bionic-security openjdk-11-jdk | 10.0.2+13-1ubuntu0.18.04.4 | bionic-updates openjdk-11-jdk | 11.0.2+9-3ubuntu1~18.04.3 | bionic-proposed See the LP bug for the java transition: https://bugs.launchpad.net/ubuntu/+source/saaj/+bug/1814133 I haven't investigate further, but I suspect it just a matter to wait for the #1814133 SRU to be completed, clear all regressions found and moving from bionic-proposed to bionic-updates. On 'Fix Released' let's re-evaluate if collectd need a rebuild or if everything works fine. - Eric ** Changed in: collectd (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1824423 Title: Bad java class file version for collectd java plugin To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/collectd/+bug/1824423/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
