new maven jobs ignore configured JDK and use default JDK on agent


      After the yum upgrade of our jenkins server from v 2.176.3 to v 2.277.1 maven jobs will not use the configured JDK, but instead use the default JDK on the slave node. This appears to only effect jobs that are created after the upgrade, as existing jobs continue to use the configured JDK.
      The master and slave nodes are running CentOS Linux release 7.9.2009.
      All relevant plugins were upgraded following the upgrade of jenkins core (current version info is attached), and 3 JDKs are defined for this Jenkins server.

      To investigate this I created a new maven job (maven command = "validate -X") and selected one of the 3 JDKs we have defined for this Jenkins server ('OpenJDK-11.0.7_10').
      If I reopen the job in the configuration editor, the jenkins log will report this error

      Mar 31, 2021 7:52:23 PM WARNING hudson.scm.SubversionSCM getModuleRoot
      No JDK named '["OpenJDK-11.0.7_10",""]' found

      and the JDK field in the UI will show "(System)", although if I directly inspect the config.xml I see this:

      [root@dapajenkin200 jenkins]# cat jobs/smf_new_2/config.xml | grep "<jdk>"

      Note that there is a change in how jenkins saves the jdk in the job configuration. In our other Jenkins server which has not been upgraded yet, the same job specifies the jdk like this

      [root@dapajenkim001 ~]# cat /jenkins/jobs/smf-trunk/config.xml | grep "<jdk>"

       The console output for a run of this job shows that it is not using the specified JDK from under the tools folder on the Jenkins slave node

      [root@dapajenkin201 ~]# ls /jenkins/tools/hudson.model.JDK/
      jdk-8u101 jdk-8u161 OpenJDK-11.0.7_10

       but rather uses the default jdk on the host:

       I did try deleting all 3 JDKs from the Global tool configuration and recreating them and the same behavior is still seen.
