About Eclipse OpenJ9
OpenJ9 ships on the quarterly JDK security clock and says almost nothing on the way past
Eclipse OpenJ9 is an alternative JVM, released in lockstep with the quarterly OpenJDK update cycle. Its release entries are pointer pages: a link to the Eclipse release plan and off-site notes, the matrix of JDK levels each version works with, branch and commit SHAs, any CVEs resolved, and a standing link to the JITServer Helm chart. No feature descriptions appear in the feed at all.
