I have a Wave Robot (which is HttpServlet ) deployed to AppEngine
The robot mapped by Guice to serve on specific url, the robot also
receives injections from Guice.
@Singleton
public class ForumBotty extends AbstractRobot {
@Inject
public ForumBotty(Injector injector, Util util, ForumPostDao
forumPostDao,
AdminConfigDao adminConfigDao, UserNotificationDao
userNotificationDao) {
this.injector = injector;
this.util = util;
this.forumPostDao = forumPostDao;
this.userNotificationDao = userNotificationDao;
this.adminConfigDao = adminConfigDao;
OAUTH_TOKEN = System.getProperty("OAUTH_TOKEN");
OAUTH_KEY = System.getProperty("OAUTH_KEY");
OAUTH_SECRET = System.getProperty("OAUTH_SECRET");
SECURITY_TOKEN = System.getProperty("SECURITY_TOKEN");
DIGEST_WAVE_DOMAIN = System.getProperty("DIGEST_WAVE_DOMAIN");
DIGEST_WAVE_ID = System.getProperty("DIGEST_WAVE_ID");
initOauth();
}
//more stuff
}
Whenever this robot receives an event - I see the exception below in
the application log on appengine. How can it be fixed?
com.google.inject.internal.FinalizableReferenceQueue <init>: Failed to
start reference finalizer thread. Reference cleanup will only occur
when new references are created.
