Alrighty! Thanks so much for the heads up, I really appreciate it. I'll leave the issue open as it feels like something that could be better fixed.
If you have any questions how to use JRakNet, feel free to open a new issue or DM me on Discord at Whirvis#0001

This looks like an issue with the Log4J dependencies. Could you try removing the dependencies for Log4J and see if it runs then?

Okay, I removed the Log4J dependencies:
<dependencies>
<dependency>
<groupId>com.whirvis</groupId>
<artifactId>jraknet</artifactId>
<version>2.12.3</version>
</dependency>
</dependencies>
But it did not help. Now, as I understand it, it requires the Log4J library to be installed. Full log:

I tested Log4J without the JRakNet dependency and it works great:
But if I add a JRakNet dependency, then even my code without using JRakNet will throw that error:
Maybe this will help somehow.

Yes, this info is very helpful! Thank you. Try changing the version of Log4J from 2.17.2 to 2.17.1, and see if that helps.
<!-- Logging interface -->
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-api</artifactId>
<version>2.17.1</version>
</dependency>
<!-- Logging implementation -->
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>2.17.1</version>
</dependency>

I have already tried doing this. Did not help.

I was able to find a solution to the problem! (Changing Log4J version from 2.17.2 to 2.17.1 did not help.)
If the JRakNet dependency is added after the Log4J dependencies, then the error will disappear:
This also works with code without using JRakNet:

Thanks for trying to help. Issue can be closed. But it would be nice if you could fix this problem or report a possible solution in the README or somewhere else.
