OpenJ9 ships on the quarterly JDK security clock and says almost nothing on the way past

Current state
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.
Where it's heading
What the feed does reliably show is the JDK support matrix advancing together — 8u, 11, 17, 21, 25 and latterly 26 all stepping forward in each release — and which cycles carried security content. Three CVEs in 0.60.0 against one in 0.59.0 and one in 0.57.0 is the only variation in an otherwise uniform sequence. Interleaved with those are single-JDK releases like 0.55.0 and 0.58.0, which track a new Java version's arrival rather than the quarterly update.
Prediction
The pattern points to the next release landing on the following quarterly OpenJDK update with a similar CVE roll-up and the JDK matrix advanced one patch level. What changes inside the JVM is not something this feed reveals.

Recent moves

    OpenJ9 0.60 resolves three CVEs across six JDK levels

    The heaviest security cycle in the visible window, closing three CVEs and advancing every supported JDK level from 8u502 through 26.0.2. As with the rest of the feed, the substance sits in the off-site release notes; what is visible here is the support matrix and the security roll-up.

    OpenJ9 0.59 closes a CVE and steps the JDK matrix forward

    A quarterly-cycle release resolving one CVE and moving all six supported JDK levels up a patch. The changelog range visible in the entry includes a JITServer buffer overrun fix, which is the only functional detail the page exposes.

    Eclipse OpenJ9 v0.58.0

    A single-JDK release targeting Java 26 with no CVEs resolved. It tracks a new Java version reaching the toolchain rather than delivering scheduled security content.

    OpenJ9 0.57 delivers the quarterly security update

    Resolves one CVE and advances the five supported JDK levels through 25.0.2. Published the same day as 0.56.0, which covers the preceding patch levels — the pair together spans two update cycles.

    Eclipse OpenJ9 v0.56.0

    A no-CVE release covering the JDK levels one step behind 0.57.0 and published alongside it. Catch-up packaging rather than a distinct delivery.

    Eclipse OpenJ9 v0.55.0

    A single-JDK release for Java 25 with no security content, following the same pattern as the later 0.58.0. Body is the standard pointer page with no feature detail.
