title: WAS serialization exception from un-used package
body: <p>I am seeing the following exception in my production WebSphere 8 server log:</p>
  
  <pre><code>WASSession    E MTMBuffWrapper getBytes write object exception. 
  e= java.io.NotSerializableException: org.apache.commons.logging.impl.Jdk14Logger
  </code></pre>
  
  <p>However the only logging package used in deployed application is <code>java.util.logging.Logger</code>.</p>
  
  <p>I am not seeing any serialization exception in my local RAD server, only in production environment.</p>
  
  <p>Any idea?</p>
