Hi Robert,
I cannot promise a fix within JCS anytime soon, as this requires a major
release (4) of JCS. So let’s see what we can do instead.

Actually, JCSServletContextListener doesn't do very much. It only makes sure
that JCS is shut down properly when the web application stops. In your case,
that saves the cache keys to the auxiliary disk cache, which may or may not be
necessary, depending on what you want to cache. If you have other means of
hooking into the shutdown process of your application (Spring Boot:
@PreDestroy), just add the line
JCS.shutdown();
somewhere.
In all other cases, this is the complete code of the servlet filter:
—8<—
public class JCSServletContextListener
implements ServletContextListener
{
/** The logger */
private static final Log log = Log.getLog( JCSServletContextListener.class );
/**
* Shutdown JCS.
*
* @see
javax.servlet.ServletContextListener#contextDestroyed(javax.servlet.ServletContextEvent)
*/
@Override
public void contextDestroyed( final ServletContextEvent arg0 )
{
log.debug( "contextDestroyed, shutting down JCS." );
JCS.shutdown();
}
/**
* This does nothing. We don't want to initialize the cache here.
*
* @see
javax.servlet.ServletContextListener#contextInitialized(javax.servlet.ServletContextEvent)
*/
@Override
public void contextInitialized( final ServletContextEvent arg0 )
{
log.debug( "contextInitialized" );
}
}
