problem with DefaultClusteringStrategy (#1498)

	Unknown opened 2 years ago I have a problem using in the configuration the value `strategy (class: tigase.server.cluster.strategy.DefaultClusteringStrategy) {}` that was valid for tigase 8.1.x, during start up of tigase 8.2.2 I get this error and then all the dependencies fails to start up Loading plugin: message-archive=1:34896 ... , version: 8.2.0-b5938/6b5a3651 [2023-05-05 14:57:42:454] [WARNING ] [ main ] Kernel.injectDependencies() : ===================== Could not initialize bean jingle (class: class tigase.xmpp.impl.push.JinglePushNotificationsExtension), skipping injection of this bean RootCause: -> tigase.kernel.KernelException: Can't inject <null> to field tigase.xmpp.impl.push.JinglePushNotificationsExtension.encryptedPushNotificationExtension [tigase.kernel.core.Kernel.inject(Kernel.java:1190)] ===================== If instead if I use `strategy (class: tigase.server.cluster.strategy.OnlineUsersCachingStrategy) {}` the startup does not give errors: `Loading plugin: message-archive=1:34896 ... , version: 8.2.0-b5938/6b5a3651 Loading component: cluster-contr :: componentInfo{Title=Tigase XMPP Server, Version=8.2.0-b5938/6b5a3651, Class=tigase.cluster.ClusterController}` what is the class to use for the default strategy to use in development? Details : Tigase version: 8.2.2-b11697
	Unknown commented 2 years ago Let me start with clarifying one thing: what is the class to use for the default strategy to use in development? You can use ACS in development without issue (there is "demo" licence in that case) Second problem is that currently the class for default strategy is `tigase.cluster.strategy.DefaultClusteringStrategy` ! Thirdly: There was a bug in one of `.toString()` methods (ref: server-1356) that actually made default strategy to fail.
	Unknown commented 2 years ago Second problem is that currently the class for default strategy is `tigase.cluster.strategy.DefaultClusteringStrategy` ! thank you, my fault Thirdly: There was a bug in one of `.toString()` methods (ref: server-1356) that actually made default strategy to fail. so this means that is better to not use the DefaultClusteringStrategy with the 8.2.2 ? (also if we do not use pubsub?)
	Unknown commented 2 years ago so this means that is better to not use the DefaultClusteringStrategy with the 8.2.2 ? (also if we do not use pubsub?) Correct. In general `DefaultClusteringStrategy` is not the best solution. For smaller deployments you can simply use single node, for bigger deployments it's better to use ACS. What's more, MUC and Pubsub don't support clustering with `DefaultClusteringStrategy`.
	Unknown commented 2 years ago ok thanks
