[JENKINS-35272] Launcher's afterDisconnect() method is called twice · jenkinsci/jenkins#17204

When a DumbSlave disconnects, the launcher's afterDisconnect() is called twice. This means, for instance, that a VM configured to shutdown and revert after a disconnect will do so twice. --- Originally reported by peppe , imported from: Launcher's afterDisconnect() method is called twice status : Open priority : Major component(s) : core label(s) : newbie-friendly resolution : Unresolved votes : 0 watchers : 1 imported : 2025-11-24 Raw content of original issue When a DumbSlave disconnects, the launcher's afterDisconnect() is called twice.

Research direction: Investigate the disconnect workflow in DumbSlave and its parent classes, focusing on the `afterDisconnect()` method in Launcher. Check whether `disconnect()` in AbstractCloudSlave or Computer calls `afterDisconnect()` redundantly. Look at the `disconnect` method chain to identify and prevent the duplicate call.
