When JRebel is used together with LiveReload, "Never Publish Automatically" needs to be turned on in Publishing setup of Server Runtime (AS/EAP) settings.

In this mode, LiveReload does not work, because new resources are never published according to the IDE.

However JRebel reloads those resources in a background.

In the opposite case ("Automatically publish after resource change"), I'm getting "Concurrent resource modification" error occasionally which might not be related to JRebel usage.
