According to Oracle Java SE Support Roadmap Oracle is ending development of OpenJDK 8 in January 2019. This means that Oracle engineers will no longer perform maintenance work on OpenJDK 8, unless you are a customer of Oracle. According to Oracle’s Java Future Release notification, “Public updates for Oracle Java SE 8 released after January 2019 will not be available for business, commercial or production use without a commercial license.”
Both Sumo Logic and our customers are “Commercial Users” of OpenJDK, not customers of Oracle, but we can continue to use versions of the OpenJDK 8 released up to and including Oracle’s January 2019 release without needing to purchase a commercial license from Oracle. However, as Oracle will not be providing public updates or patches to this older version of Java, Sumo Logic will be upgrading it’s collectors to Java 11 in Q1 of 2019.
As part of the upgrade to Java 11 Sumo Logic will be selecting a new JRE vendor, ending use of Oracle’s OpenJDK. Sumo Logic has been evaluating several candidate JRE vendors as a replacement and is in the process finalizing their selection in preparation for release in the collector in April 2019.
