title: how to prevent jsp tags from being reused after being classloaded
body: <p>I have a problem where certain attributes in tag files stick around for the next time the tag is used.</p>
  
  <p>I think this is because the Tag class is being classloaded, and then that same instance is reused for every invocation. So attributes that i do not set in later invocations are not null like i would expect them to be, and contain stale values!</p>
  
  <p>I want this to not happen any more. Does anyone know what setting controls that in tomcat 6?</p>
