ECS Object Client SDK for Java v4.0.0

This is a major release that uplifts the OBS Java SDK from Java 11 to Java 17(compatible with 21/25). It introduces a fully modernized HTTP transport layer, refreshed dependencies and an updated test infrastructure. Java 8 and Java 11 are no longer supported in this release line — use the [3.x releases] (https://github.com/EMCECS/ecs-object-client-java/releases) for Java 8/11 compatibility.

Highlights:

• Upgraded Java source/target compatibility to Java 17; tested on JDK 17, JDK 21 and JDK 25
• Migrated HTTP transport from Jersey 1.19.4 (JAX-RS 1.x) to Jersey 2.47 (JAX-RS 2.x)
• Upgraded smart-client-ecs to 4.0.0 (GA)
• Upgraded Jackson from 2.12.x to 2.17.3
• Upgraded commons-codec to 1.17.1, dom4j to 2.1.4, slf4j-api to 2.0.16, log4j-slf4j2-impl to 2.24.3
• Migrated test framework from JUnit 4 to JUnit Jupiter 5.11.4; upgraded Mockito to 5.14.2

⚠️ Breaking changes:

• Java 8 and Java 11 are no longer supported. Minimum required JDK is Java 17.
• Jersey 1.x APIs have been removed. Direct Jersey 1.x client code must be migrated to Jersey 2.x.
