Per the "Upgrading Jenkins Java version from 8 to 11" page [1]: > All agents must be running on the same JVM version as the master (because of > how masters and agents communicate). If you're upgrading your Jenkins master > to run on Java 11, you also need to upgrade the JVM on your agents.
Per the "Java requirements" page [2]: > If you use Swarm Plugin to create agents, JRE version must be equal to the > version of the master Why is there a requirement for agents to be running on the same JRE version as the master? Is this because backwards-incompatible changes have been made to serializable classes in the Java 11 runtime? If so, could someone please elaborate?
