Summary of Changes
Hello @Alesvoy, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request adds a new App Engine sample for the App Identity API, designed to run on the Java 21 runtime. The sample showcases various aspects of the App Identity service, such as retrieving application identity information, digitally signing data, and using the application's identity to authenticate with other Google Cloud services. It provides a practical example for developers looking to integrate App Identity features into their Java 21 App Engine applications.
Highlights
- New Java 21 App Engine Sample: This pull request introduces a brand new sample for the App Identity API, specifically configured to run on the Java 21 runtime environment within Google App Engine.
- Comprehensive App Identity Demonstrations: The sample demonstrates key functionalities of the App Identity API, including retrieving the default version hostname, signing arbitrary data and verifying its signature, and obtaining access tokens to authenticate with other Google APIs (e.g., URL Shortener).
- Compiler Version Note: While the
appengine-web.xmlexplicitly sets the runtime tojava21, thepom.xmlstill specifiesmaven.compiler.targetandmaven.compiler.sourceas1.8. This means the code is compiled for Java 8 compatibility, even when running on a Java 21 environment. This might be an area for future enhancement to leverage Java 21 language features.

Code Review
This pull request aims to upgrade the App Identity sample to Java 21. While this is a good initiative, there are several critical issues that need to be addressed. The pom.xml still targets Java 1.8 and uses the outdated javax.servlet API instead of jakarta.servlet required for modern runtimes. Furthermore, the URL shortener example uses a Google API that was deprecated and shut down in 2019, making that part of the sample non-functional. There are also other high and medium severity issues detailed in the comments, such as security vulnerabilities and outdated practices. Please address these points to ensure the sample is correct, secure, and up-to-date for Java 21.
