Hot Swap doesn't work with Grails application

I am developing grails (4.0.8) web application. I have hot-swap agent for groovy code enabled. I am running an grails application in debug mode. After a change in groovy class there is a message in the server console: "File *.groovy changed, recompiling..." but the classes are not swapped. Hot swapping doesn't work and it's required to restart application to see the changes.

To cause groovy file recompile, after a change I just hit cmd+s / ctrl+s. In older versions of grails that was enough to see the changes on the server.

Reproduce the problem with a Grails 4.0.8 application running in debug mode and HotSwapAgent enabled, then edit a Groovy class and save it with cmd+s or ctrl+s. Compare the console's recompilation message with the running application; done means Groovy class changes take effect without restarting the application.
