I created a PR with a repro project. Just start the server and then the client application.

I can confirm the failure with Boot 2.0 RC2 (and Spring Framework 5.0 RC2). Upgrading to the latest Boot 2.0 snapshot (and hence picking up the latest Spring Framework 5.0 snapshot) works as expected.

The big change in this area since RC2 that probably explains the fix is #19097.
