title: Hazelcast: programmatic configuration for logging in debug mode
body: <p>Trying to configure <code>slf4j</code> to log in DEBUG mode, but get only INFO logs. What am I doing wrong?</p>
  
  <pre><code>Config hazelcastConfig = new Config("HazelcastConfig");
  hazelcastConfig.getProperties().put("hazelcast.logging.type", "sl4j");
  hazelcastConfig.getProperties().put("slf4j.logger.com.hazelcast", "debug");
  Hazelcast.newHazelcastInstance(hazelcastConfig);
  </code></pre>
