Hi everyone, I am using the `java-jwt` library in my project, which currently runs on Java 8. I am planning to migrate from Java 8 to Java 21 and am investigating compatible versions of each library for Java 21. I found that the latest version of `java-jwt` (4.4.0 as of August 2024) is compatible with Java 8, 11, and 17, but there is no mention of support for Java 21. Could someone confirm whether `java-jwt` version 4.4.0 supports Java 21? This is my first time upgrading the Java version, so any assistance would be greatly appreciated. Thank you! ---

Hi @rikkyrice Welcome to the Auth0 Community! It would be best if you could open an issue in the [Java-JWT GitHub repository](https://github.com/auth0/java-jwt/issues) and share the link to the issue here. I will ping the repo owner. Thanks Dawid ---

Hi @rikkyrice and other community folks! Our Engineering team doesn’t see any reason why the Java-JWT library wouldn’t be compatible with Java 21.
