    - #### propertyChange

          public void propertyChange(PropertyChangeEvent event)

      Process property change events from our associated Context.

      Part of this method implementation was taken from StandardManager. The sessionTimeout can be changed in the web.xml which is processed after the context.xml. The context (and the default session timeout) would already have been set in this Manager. This is the way to get the new session timeout value specified in the web.xml.

      The precedence order for setting the session timeout value is:

      1. the max inactive interval is set based on the Manager defined in the context.xml
      2. the max inactive interval is then overwritten by the value of the Context's session timeout when setContainer is called
      3. the max inactive interval is then overwritten by the value of the session-timeout specified in the web.xml (if any)
      Specified by:
        `propertyChange` in interface `PropertyChangeListener`
      Parameters:
        `event` - The property change event that has occurred
