Code Review

This pull request, automatically generated by Snyk, proposes upgrading com.google.protobuf:protobuf-java from 3.25.3 to 4.33.2. While dependency updates are generally good, this particular change introduces critical issues. The target version 4.33.2 does not seem to exist in public repositories. More importantly, this is a major version upgrade that requires Java 8, but the project is built with Java 7, which would break the build. Furthermore, the security vulnerability cited as the reason for this upgrade is already addressed by the current version 3.25.3. Therefore, I recommend rejecting this pull request.

<project.jsr305.version>3.0.2</project.jsr305.version>
<project.gson.version>2.8.6</project.gson.version>
<project.protobuf-java.version>3.25.3</project.protobuf-java.version>
<project.protobuf-java.version>4.33.2</project.protobuf-java.version>

critical

This upgrade to protobuf-java:4.33.2 is problematic for several reasons and will likely break the project build.

  1. Java Version Incompatibility: The protobuf-java 4.x library requires Java 8 or higher. This project is currently configured to use Java 7, as seen from the maven-compiler-plugin configuration (<source>1.7</source>, <target>1.7</target>). Attempting to use this version will result in build failures.

  2. Non-existent Version: The version 4.33.2 for com.google.protobuf:protobuf-java does not appear to be available in public Maven repositories like Maven Central. This suggests there might be an error in the target version specified.

  3. Unnecessary for Vulnerability Fix: The pull request description states this upgrade is to fix vulnerability SNYK-JAVA-COMGOOGLEPROTOBUF-8055227. However, according to Snyk's own vulnerability database, version 3.25.3 (the version currently in use) is a patched version and is not vulnerable. Therefore, this major upgrade seems unnecessary from a security perspective.

Given these critical issues, this pull request should not be merged in its current state. The dependency should remain at 3.25.3.
