    • Jenkins 2.263.4
      RH7 Linux, no container (slaves and master)
      remoting 4.5
      openJDK jdk-11.0.9.1+1 on slaves and master
      (openJDK jdk8u275-b01 for crosscheck on one slave)

      On start of a slave using openJDK jdk-11.0.9.1+1 on slaves and master I get in the log:

      --------------

      <===[JENKINS REMOTING CAPACITY]===>channel started
      Remoting version: 4.5
      This is a Unix agent
      WARNING: An illegal reflective access operation has occurred

      --------------

      The bold warning makes me a little bit nervous....

      All these warnings are not present, if I use openJDK jdk8u275-b01 instead. (Everything else unchanged)

      There is a similar report referring to Windows and (Sun) JDK9: https://issues.jenkins.io/browse/JENKINS-46631
      And on JDK11, but referring to "after installing the selenium plugin" https://issues.jenkins.io/browse/JENKINS-64831

      (We DON'T have this plugin installed)

      I'm running Jenkins with JDK11, because in my understanding the switch is pending; I'm using openJDK because Sun/Oracle would need a license in my understanding.
