Hi,

i am using payara 5 atm at the version 2021.3. I was wondering since there is a slf4j dependency, should i be able to use it? I can find it in the embedded-all jar for the server, so i assumed it is working and configured out of the box, but i get the following message:

```auto

[2022-11-18T10:37:23.670+0100] [Payara 5.2021.10] [SEVERE] [] [] [tid: _ThreadID=7626 _ThreadName=admin-thread-pool::admin-listener(3)] [timeMillis: 1668764243670] [levelValue: 1000] [[
  SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".]]

[2022-11-18T10:37:23.671+0100] [Payara 5.2021.10] [SEVERE] [] [] [tid: _ThreadID=7626 _ThreadName=admin-thread-pool::admin-listener(3)] [timeMillis: 1668764243671] [levelValue: 1000] [[
  SLF4J: Defaulting to no-operation (NOP) logger implementation]]

```

This lets me to believe that it is not working.

i only found an old stack overflow post saying the slf4j comes with another dependency and should not be loaded, and i am not sure if i shoudl use it or not. Also if i want to use it, is there another dependency that i could include to make it work with payara, like logback ect and doesn’t that trigger a conflict?  
I suppose i could load logback in the payara implementation itself so it starts up loading that, but i am not sure if that would be a viable option.

Cheers, Sebastian
