What is Apache OpenNLP?

Three parallel lines, one shared job: making model files safe to load

OpenNLP maintains three branches at once — a 1.9.x line kept alive because Lucene and Solr 8.x depend on it, a 2.5.x production line, and a 3.0.0 milestone series. Recent releases across all three are driven by the same security work: XXE in the dictionary parser, arbitrary class instantiation via crafted model archives, untrusted Java deserialization in SvmDoccatModel, and OOM-by-array-allocation. Alongside that, the 3.0 milestones are quietly rebuilding the text-processing core.

What is GeoTools?

GeoTools is migrating off dead Java imaging infrastructure that the whole GeoServer stack sits on

GeoTools runs three release branches at once — 33.x for Java 11, 34.x for Java 17, and now 35.0 — with the same GEOT ticket numbers appearing across all of them as fixes get backported. The 34.0 release in October 2025 made Java 17 the stable line; 35.0 in June 2026 is the structural one, migrating the raster core to ImageN, moving to Jakarta EE 10 and Jackson 3, and dropping the H2-based indexes and gt-jdbc-h2 entirely. Cloud-native formats are the other active area: GeoParquet, PMTiles and DGGS support have all arrived within the last year.

Apache OpenNLP vs GeoTools: editorial side-by-side

A5.0

Three parallel lines, one shared job: making model files safe to load

◆ Current state

OpenNLP maintains three branches at once — a 1.9.x line kept alive because Lucene and Solr 8.x depend on it, a 2.5.x production line, and a 3.0.0 milestone series. Recent releases across all three are driven by the same security work: XXE in the dictionary parser, arbitrary class instantiation via crafted model archives, untrusted Java deserialization in SvmDoccatModel, and OOM-by-array-allocation. Alongside that, the 3.0 milestones are quietly rebuilding the text-processing core.

◆ Where it's heading

Two arcs run in parallel. The defensive one treats model archives as untrusted input — an allowlist before Class.forName, ObjectInputFilter on deserialization, secure XML processing — which is the right posture now that models are distributed artifacts. The constructive one, concentrated in 3.0.0-M4 and M5, layers in a UAX#29 word tokenizer, a Unicode normalization and confusables engine, an offset/alignment layer, and ONNX-hosted transformer models including RoBERTa.

◆ Prediction

The 3.0 milestone series looks close to feature-complete on the tokenization and normalization stack, so the next milestones should shift toward stabilization ahead of a 3.0.0 release while 2.5.x keeps receiving backported fixes.

GeoTools is migrating off dead Java imaging infrastructure that the whole GeoServer stack sits on

◆ Current state

GeoTools runs three release branches at once — 33.x for Java 11, 34.x for Java 17, and now 35.0 — with the same GEOT ticket numbers appearing across all of them as fixes get backported. The 34.0 release in October 2025 made Java 17 the stable line; 35.0 in June 2026 is the structural one, migrating the raster core to ImageN, moving to Jakarta EE 10 and Jackson 3, and dropping the H2-based indexes and gt-jdbc-h2 entirely. Cloud-native formats are the other active area: GeoParquet, PMTiles and DGGS support have all arrived within the last year.

◆ Where it's heading

The library is replacing foundations it can no longer maintain. Java Advanced Imaging has been unmaintained for well over a decade, and the move to ImageN — staged across 34.0's JAITools-to-JAI-Ext step and 35.0's full migration — is the exit from that dependency. The same pass removes H2, upgrades every JDBC driver in the tree, and standardises entity resolution across the library. Format work runs alongside it and points at object storage: GeoParquet with AWS credential-chain auth and covering-bbox filtering, PMTiles reading, curved geometries in GeoPackage.

◆ Prediction

With ImageN and Jakarta EE 10 landed in 35.0, expect the 35.x patches to be dominated by fallout from those migrations in the raster and mosaic paths, where the release already shows reprojection and overview-decimation bugs. The 33.x Java 11 branch is receiving only backports and looks close to retirement.
