Hi Les,
I am running into the same issue when configuring Shiro programatically with
Guice (I do not use a shiro.ini file). When I shutdown Tomcat, there are
several ehcache threads that are not getting destroyed. I tried setting the
system property CacheManager.ENABLE_SHUTDOWN_HOOK_PROPERTY=TRUE and it did
not solve the problem.
I have also been attempting to force cleanup in my
GuiceServletContextListener by overriding contextDestroyed. My thought was
to get a handle to my realm and force shutdown through the CacheManager.
This approach is not working for me. I see that my contextDestroyed gets
hit, but calling shutdown() on my CacheManager, is not destroying the
threads.
Here is what my contextDestroyed looks like:
@Override
public void contextDestroyed(ServletContextEvent servletContextEvent) {
CustomRealm realm = injector.getInstance(CustomRealm.class);
if(realm instanceof AuthorizingRealm) {
CacheManager manager = realm.getCacheManager();
if(manager instanceof EhCacheManager) {
EhCacheManager ehManager = (EhCacheManager)manager;
ehManager.getCacheManager().shutdown();
}
}
}
Any thoughts would be greatly appreciated.
Thanks,
-Shane
