How to find and remove duplicate logging implementations on classpath

If you have multiple logging implementations on the classpath, one will be picked in a non-deterministic ("random") way. You may see logging like this.

15:04:56.264 [ERROR] [system.err] SLF4J: Class path contains multiple SLF4J bindings.
