What is Apache OpenNLP?

Apache OpenNLP ships 3.0.0 final, closing a milestone track that ran since spring.

Apache OpenNLP runs three release lines: 1.9.x for Lucene and Solr 8 users, 2.5.x as the stable line, and the 3.0 track that went through six milestones. On 12 November the project tagged 3.0.0 final alongside a 2.5.13 patch, again shipping both lines on the same day. The tags carry no release notes in the feed, so what changed since 3.0.0-M6 is not visible here.

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.

Apache OpenNLP vs Eclipse OpenJ9: editorial side-by-side

A5.0

Apache OpenNLP ships 3.0.0 final, closing a milestone track that ran since spring.

◆ Current state

Apache OpenNLP runs three release lines: 1.9.x for Lucene and Solr 8 users, 2.5.x as the stable line, and the 3.0 track that went through six milestones. On 12 November the project tagged 3.0.0 final alongside a 2.5.13 patch, again shipping both lines on the same day. The tags carry no release notes in the feed, so what changed since 3.0.0-M6 is not visible here.

◆ Where it's heading

The 3.0 milestones combined security hardening (deserialization and XXE fixes, model-loading allowlists) with new text tooling such as the Unicode normalization engine and a SymSpell spell checker, while 2.5.x added RoBERTa inference through ONNX Runtime. With 3.0.0 out, the 2.5 line is likely to move to backports only, and new work should land on 3.x.

◆ Prediction

Expect a 3.0.1 patch and continued 2.5.x security backports; whether 1.9.x gets further releases is unclear from these entries.

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.
