Upgrade Java Runtime to Java 11 and Modernize Codebase

[aman-cn]

Objective:
The main goal of this issue is to upgrade the Java runtime of our repository from Java 8 to Java 11. Along with the runtime upgrade, we need to ensure that all the associated libraries, frameworks, and dependencies are also upgraded to their compatible versions. The upgraded codebase should compile successfully and pass all the existing test cases to maintain the expected behavior and functionality.

Requirements:

Upgrade the Java runtime from Java 8 to Java 11.
Identify all the libraries, frameworks, and dependencies used in the project and upgrade them to their latest versions compatible with Java 11.
Verify compatibility among the upgraded components to avoid any conflicts or breaking changes.
Refactor the codebase wherever necessary to adapt to the changes introduced by Java 11 and the upgraded dependencies.
Replace any outdated or deprecated 3rd party dependencies or libraries with better alternatives to modernize the codebase.
Ensure that the upgraded codebase compiles successfully without any errors.
Run all the existing test cases and make sure they pass after the upgrade process.
Perform thorough testing to verify that the application behaves as expected and maintains the same functionality as before.
Expected Outcomes:

The Java runtime of the repository should be successfully upgraded to Java 11.
All the libraries, frameworks, and dependencies should be upgraded to their compatible versions.
The codebase should be refactored and modernized by replacing outdated or deprecated components with better alternatives.
The upgraded codebase should compile successfully without any errors.
All the existing test cases should pass, ensuring the expected behavior and functionality of the application.
The application should be thoroughly tested to verify that it works correctly after the upgrade process.
Steps to Reproduce:

Checkout the latest version of the codebase from the repository.
Update the Java runtime to Java 11 in the project's configuration files (e.g., pom.xml for Maven, build.gradle for Gradle).
Identify and upgrade all the libraries, frameworks, and dependencies to their compatible versions for Java 11.
Refactor the codebase to adapt to any changes introduced by Java 11 and the upgraded dependencies.
Identify any outdated or deprecated 3rd party dependencies or libraries and replace them with better alternatives.
Compile the upgraded codebase and fix any compilation errors that may arise.
Run all the existing test cases and ensure they pass successfully.
Perform additional testing to verify the application's behavior and functionality after the upgrade.
Additional Considerations:

Make sure to update the project's documentation, including the README file, to reflect the changes made during the upgrade process.
Consider updating any CI/CD pipelines or build configurations to use Java 11 and the upgraded dependencies.
If there are any breaking changes or significant modifications required, communicate them clearly to the team and stakeholders.
Provide clear instructions or a step-by-step guide for other developers to replicate the upgrade process in their local development environments.
