Template change causing reload error about play-scala-isolated-slick-example HOT 4 OPEN

You call ApplicationLifecycle.addShutdownHook, since recompilation usually means the server is going to be bounced:

I thought it was already done properly here: https://github.com/playframework/play-scala-isolated-slick-example/blob/2.6.x/app/Module.scala#L33

Does it need to be changed? It calls the shutdown hook when I stop the server by hitting enter but it is not calling the hook after a template recompilation / server reload.

That certainly looks right. Can you attach a debugger and set a breakpoint? You can use https://www.playframework.com/documentation/2.6.x/PlayConsole#debugging to set up the JDPA port and then attach to local process from IntelliJ IDEA.

Seems to be an issue with the connection pool not getting restarted/closed on the reload.
Work around for this issue is to use connectionPool=disabled for the DatabaseConfig
