---------------------------------------------------------------

As Konrad said, using slf4j is a deliberate decision, and is done in many other projects as well. It's unfortunate that you have a problem with a class conflict, and it would be good to understand what exactly goes wrong here.

I find out a bit funny that, in another ticket, you just asked for adding an (optional) runtime dependency to make things easier for you to configure, and here you ask to remove a required dependency.

> Life is too short to deal with exceptions like this one:
> java.lang.LinkageError: loader constraint violation: when resolving method 'org.slf4j.ILoggerFactory org.slf4j.impl.StaticLoggerBinder.getLoggerFactory()' the class loader org.apache.catalina.loader.ParallelWebappClassLoader @4bd217c of the current class, org/slf4j/LoggerFactory, and the class loader java.net.URLClassLoader @7907ec20 for the method's defining class, org/slf4j/impl/StaticLoggerBinder, have different Class objects for the type org/slf4j/ILoggerFactory used in the signature (org.slf4j.LoggerFactory is in unnamed module of loader org.apache.catalina.loader.ParallelWebappClassLoader @4bd217c, parent loader java.net.URLClassLoader @7907ec20; org.slf4j.impl.StaticLoggerBinder is in unnamed module of loader java.net.URLClassLoader @7907ec20, parent loader 'app')
> Remove slf4j and replace with the java default behaviour.
