Re: [Dev] [BPS][Carbon] A way to delay shutdown of hazelcast instance at server shutdown
Hi, Thanks Indika and Shashika. This should solve my problem.

No. Hazelcast anyway stop after bundle deactivate. If you want to do some task before deactivate all bundles, then you can use WaitBeforeShutdownObserver. It will block shutting down until task completion. We had a requirement of complete all messaging task before server gracefully shutting down.

Hi, I was trying the shashikap's suggestion. It seem to be still we can't guarantee the scheduler shuts down first, since these two may run in different threads. @Indika, If we disable the hazelcast shutdown hook, we will have to manually shutdown the hazelcast instance right?

Re: [Dev] [BPS][Carbon] A way to delay shutdown of hazelcast instance at server shutdown
HI Vinod, AFAIK you have to implement [1] in BPS to handle these scenario in server shutdown. [1] https://github.com/wso2/carbon4-kernel/blob/master/core/org.wso2.carbon.core/src/main/java/org/wso2/carbon/core/ServerShutdownHandler.java Thank you.
