title: How to change the logging level for a particular package using java.util.logging.Logger
body: <p>Say I have the following config for the java util logger I am using</p>
  
  <pre><code>handlers=java.util.logging.ConsoleHandler
  .level=INFO
  java.util.logging.ConsoleHandler.level=ALL
  </code></pre>
  
  <p>Now I want to restrict all classes that are in the package org.apache.solr.* to only log WARNING or higher levels. How to I do this through configuration only? ( similar to how we use category in log4j)</p>
