[jira] [Comment Edited] (CASSANDRA-15624) Avoid lazy initializing shut down instances when trying to send them messages

    [ https://issues.apache.org/jira/browse/CASSANDRA-15624?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17089774#comment-17089774 ]

-------------------------------------------------------------------------

In talking with [~marcuse], he told me this is actually an improvement around the in-jvm tests and it's not currently breaking any tests or making them flakey.

I did some investigation and it seems that with the recent changes in CASSANDRA-15501 ([https://github.com/apache/cassandra/commit/16f639af94f56cdc7145299730278e27a9113e2e]), the in-jvm Wrapper instance will now check if the delegate is null and prevent any operations on a shutdown node. Instead of failing silently or throw an NPE, it will now throw an IllegalStateException telling that "Can't use shut down instances, delegate is null".

[~marcuse] Do you think there's anything else we need to tackle in this ticket? /cc [~ifesdjeen]

Either way, being an improvement ticket, I don't think this is a blocker for 4.0 at this point and we can probably move it out. Any objections?

> We currently use {{to.broadcastAddressAndPort()}} when figuring out if we should send a message to an instance, if that instance has been shut down it will get re-initialized but not startup:ed which makes the tests fail.
