Samuel Gabriel please refer to https://jenkins.io/doc/administration/requirements/java/.
Jenkins does not, and will not, support JDK 10.
So in your case, given we are about to announce the JDK 11 Preview (https://www.meetup.com/fr-FR/Jenkins-online-meetup/events/257008190/), you might want to upgrade to JDK 11 given anyway you're already using a setup using unreleased/preview components. We will for sure warmly welcome feedback about the Preview.
If your setup is a production one, it might be better to go back to JDK 8 until we reach GA for JDK 11, but that is ultimately your choice, now you know the support status.
Thanks for your understanding.
