Description
Can't run WebProtégé in SuperDev Mode using maven. I follow the steps on the repository's readme and I'm faced with errors.

To Reproduce
Steps to reproduce the behavior:

1. Build WebProtégé acording to the repo's readme.
2. Execute the commands mvn gwt:codeserver and mvn -Denv=dev tomcat7:run in different terminal windows.
3. Get error message in the terminal window in which the command mvn -Denv=dev tomcat7:run was executed.

Expected behavior
Expected WebProtégé to be launched without errors in SuperDev Mode at http://localhost:8080/

Screenshots
Won't post a screenshot as the code error log is not small. Error log is instead attached as a .txt file.

• OS: Ubuntu
• Version: 22.0.4

Additional context
From reading the repository's readme, I am not certain if system pre-requisites exist in order to be able to run WebProtégé in this manner. If they do, my current system may very well not be in compliance with them, which may be the cause of this error. Anyhow, I'd be thankful if you could detail what these system characteristics would be.

Thanks in advance and if anything else is needed from my side, let me know.
