Purpose

The Ballerina distribution release scan flagged seven Jackson vulnerabilities in openapi-bal-task-plugin-2.4.3.jar, which bundles jackson-core and jackson-databind 2.22.1. The findings include denial-of-service and unsafe deserialization issues. Release scan

This PR imports the Jackson 2.22.4 BOM in gradle/javaProject.gradle to align the Jackson dependencies used by the OpenAPI task plugin and other Java subprojects that use the shared script. The BOM replaces the previous jackson-databind:2.15.3 constraint.

The reported CVEs are CVE-2026-89407, CVE-2026-89425, CVE-2026-68497, CVE-2026-91776, CVE-2026-91777, CVE-2026-19032, and CVE-2026-83557.

Updated Jackson dependency management by setting jacksonVersion to 2.22.4 and adding the Jackson BOM to implementation dependencies. Removed the explicit jackson-databind constraint at version 2.15.3.

Walkthrough

The Gradle build sets the Jackson version to 2.22.4 and uses the Jackson BOM for implementation dependencies. It removes the fixed jackson-databind version constraint of 2.15.3.
