docs: Configures JUL (java.util.logging) using the logging.properties file located in this package.
  Only use this method for testing purposes, clients should configure logging themselves - that
  is you need to provide a logging bridge for SLF4J compatible to your logging infrastructure, or
  use SLF4J no-op logger.
