📝 Walkthrough

Summary

This pull request updates the project to use Apache Commons Lang 3 (version 3.18.0) in place of the legacy Apache Commons Lang 2 library. The migration involves updating dependencies and imports throughout the codebase.

Changes

Dependency Updates:

• Updated root pom.xml dependency management to reference org.apache.commons:commons-lang3 (v3.18.0) instead of commons-lang
• Updated modules/charon-core/pom.xml with corresponding dependency and OSGi import package declarations

Import Updates:
Systematically updated imports across 21 Java files in the following modules:

• modules/charon-core/src/main/java/org/wso2/charon3/core/ (attributes, config, encoder, objects, protocol, schema, utils)
• modules/charon-utils/src/main/java/org/wso2/charon3/utils/

Specifically, the following utility class imports were updated:

• org.apache.commons.lang.StringUtils → org.apache.commons.lang3.StringUtils
• org.apache.commons.lang.ArrayUtils → org.apache.commons.lang3.ArrayUtils
• org.apache.commons.lang.NumberUtils → org.apache.commons.lang3.NumberUtils

All existing code logic and method usage remain unchanged, as the Commons Lang 3 library provides compatible implementations of these utility classes.

Impact

• Scope: 24 files modified (1 POM file, 23 Java source files)
• Behavioral Changes: None - the migration maintains functional equivalence with the previous implementation
• API Compatibility: The Commons Lang 3 utility APIs are compatible with existing usage patterns in the codebase

Walkthrough

The pull request migrates the charon project from Apache Commons Lang 2 (commons-lang) to Apache Commons Lang 3 (commons-lang3, version 3.18.0). The root pom.xml updates the managed dependency artifact, version property, and OSGi version range. The charon-core module's pom.xml correspondingly updates the local dependency and OSGi Import-Package directive to target org.apache.commons.lang3.*. Across 20 Java source files in charon-core and charon-utils, import statements for StringUtils, ArrayUtils, and NumberUtils are updated to the org.apache.commons.lang3 package. No logic, method signatures, or public API contracts are altered in any file.
