What is Eclipse OpenJ9?

OpenJ9 follows its 0.63 CVE release with a notes-less 0.63.0.1 respin.

Eclipse OpenJ9, IBM's alternative JVM, released 0.63.0 on October 28 with several CVE fixes and JITServer hardening against oversized and malformed messages. A 0.63.0.1 point tag followed on November 3 with only repository hashes. Earlier 2026 releases added JDK 26 support, moved the build fully to CMake, and patched CVEs in most cycles.

What is Manticore Search?

Manticore keeps patching 31.x, now fixing a FREEZE crash and a DocID ordering bug.

Manticore Search's 31.x tags remain fixes rather than features. 31.0.7 restored string COUNT(DISTINCT) speed after a collation fix had doubled it to 2.4 s, and 31.0.18 bumped the Buddy sidecar for PHP 8.5. 31.0.19 fixes deferred real-time kills that sorted document IDs as signed numbers, and 31.0.21 stops FREEZE from crashing when it includes a distributed table.

Eclipse OpenJ9 vs Manticore Search: editorial side-by-side

E5.0

OpenJ9 follows its 0.63 CVE release with a notes-less 0.63.0.1 respin.

◆ Current state

Eclipse OpenJ9, IBM's alternative JVM, released 0.63.0 on October 28 with several CVE fixes and JITServer hardening against oversized and malformed messages. A 0.63.0.1 point tag followed on November 3 with only repository hashes. Earlier 2026 releases added JDK 26 support, moved the build fully to CMake, and patched CVEs in most cycles.

◆ Where it's heading

OpenJ9 tracks the OpenJDK quarterly update train, with security fixes in most releases and JITServer getting the most attention. A quick point release after 0.63.0 usually means a fix for a regression or a missed JDK update, but the tag doesn't say which.

◆ Prediction

The next regular release should land with the January OpenJDK updates; what prompted 0.63.0.1 is unclear from the entries.

M5.0

Manticore keeps patching 31.x, now fixing a FREEZE crash and a DocID ordering bug.

◆ Current state

Manticore Search's 31.x tags remain fixes rather than features. 31.0.7 restored string COUNT(DISTINCT) speed after a collation fix had doubled it to 2.4 s, and 31.0.18 bumped the Buddy sidecar for PHP 8.5. 31.0.19 fixes deferred real-time kills that sorted document IDs as signed numbers, and 31.0.21 stops FREEZE from crashing when it includes a distributed table.

◆ Where it's heading

The 31.x line is in steady correctness work, with several tags a week and each fixing one edge case in real-time tables, backups or query paths. No feature work has shown up in the feed since 31.0 began.

◆ Prediction

Expect more single-fix 31.0.x tags; the entries give no sign of when the next feature release lands.
