void clear method() of Hashtable class. Remove method removes all
key value pairs contained in Hashtable.

/**

* stored.
* <p>
* Message is stored in String format and must be unmarshalled into XMLObject. Call to this
* method may thus be expensive.
* <p>
* Messages are automatically cleared upon successful reception, as we presume that there
* are never multiple ongoing SAML exchanges for the same session. This saves memory used by
* the session.

* @param messageID ID of message to retrieve
* @return message found or null
