Check openjdk-redhat-version

Overview

This plugin lets you track if Java (OpenJDK Red Hat Version) is End-of-Life (EOL). To compare against the current/installed version of Java, the check has to run on the Java server itself.

This check plugin alerts n days before or after the EOL date is reached. Optionally, it can also alert on available major, minor or patch releases (each independently).
