Since upgrading STS to version 3.9.0, it seems there is a new issue with setting the server.port property via VM args in Launch configurations. On the Arguments tab of the Debug/Run configurations screen, in the VM arguments window, I have -Dserver.port=8123. This launch configuration has been working for over 6 months, but after upgrading to 3.9.0, now I'm getting a NumberFormat exception related to parsing the port number. Caused by: java.lang.NumberFormatException: For input string: "8123-noverify" If I move the port number assignment into the application.yml properties file, the issue goes away. The issue also goes away if I use the Spring arg format --server.port=8123 in the launch config. The problem is restricted to parsing the -Dserver.port= VM arg. I don't know if the issue affects other VM args besides server.port.
Edit: (stack trace)

Your problem's caused by a bug. It's been fixed but, at the time of writing, it has yet to make it into a release.
You can work around the problem by opening preferences, navigating to Spring -> Boot and clearing Java VM arguments to trigger app's fast startup which, by default, contains -noverify -XX:TieredStopAtLevel=1.
