Refactor deprecated Locale constructor and @MockBean annotation

[Copilot]

Description

Resolves deprecated API usage warnings from Java 19+ and Spring Boot 3.4+.

Changes

Locale constructor (Java 19+)

• Replaced new Locale("und") with Locale.forLanguageTag("und") in LanguageMap
• Updated test files to use forLanguageTag() for consistency
• Fixed case sensitivity: Locale.forLanguageTag("UND") → Locale.forLanguageTag("und")

The new approach creates Locale.ROOT internally for "und", aligning with RFC 5646 and existing Jackson deserialization behavior via StrictLocaleDeserializer.

Spring Boot test annotation (3.4+)

• Replaced @MockBean with @MockitoBean in StatementsControllerTest
• Updated import: org.springframework.boot.test.mock.mockito → org.springframework.test.context.bean.override.mockito

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• checkstyle.org
  • Triggering command: /opt/hostedtoolcache/CodeQL/2.23.3/x64/codeql/tools/linux64/java/bin/java -jar /opt/hostedtoolcache/CodeQL/2.23.3/x64/codeql/xml/tools/xml-extractor.jar --fileList=/home/REDACTED/work/xapi-java/.codeql-scratch/dbs/java/working/files-to-index9931116187965694957.list --sourceArchiveDir=/home/REDACTED/work/xapi-java/.codeql-scratch/dbs/java/src --outputDir=/home/REDACTED/work/xapi-java/.codeql-scratch/dbs/java/trap/java (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

This section details on the original issue you should resolve

<issue_title>[Chore]: Find and refactor deprecated code calls</issue_title>
<issue_description>### What

Audit the entire codebase to locate all usages of deprecated methods, classes, or APIs. Once found, refactor these calls to use recommended or updated alternatives and ensure the code remains functionally correct. Verify all changes with relevant tests.

Why

Refactoring deprecated code is essential to maintain long-term code health, avoid potential runtime issues, and keep the project in line with current best practices. This reduces technical debt and increases maintainability.

Notes

Review recent Java and library updates for possible new recommended replacements. If any deprecated code cannot be directly refactored, note exceptions and rationale in the PR.</issue_description>
