> Should I upgrade the plugin to JDK 9+ or it's not mandatory because from SLA perspective Jenkins should be upgraded? I believe jenkins core is still minimum requirement of java 8. According to https://jenkins.io/doc/administration/requirements/java/ 9 and 10 are explicitly not supported. So combined with your last question, you could potentially have users that can't use your plugin. I believe there's ways to mark your plugin as 11 only.
