Environment:

• Ubuntu 20.04
• Apache Maven 3.8.3
• Java version: 17.0.1-oracle or 11.0.12-open

Having studied the tests, I did not understand what exactly was broken: the tests themselves or the source code.
There may be a problem in the system environment.
Ideally, it would be to move the build of the project to Docker, where the environment is exactly stable. For example based on FROM maven:3.8.4<jdkVersion>. Here are the versions.
