JDK client cannot connect to secure WebSocket since Java 11

Since Java 11, when using the JDK standalone client instead of the Grizzly client to connect to a wss:// URL, the connectToServer method hangs for 30 seconds and then throws the following exception:

> Exception in thread "main" javax.websocket.DeploymentException: Handshake response not received.

When using Java 8, 9 or 10 the same test works. Also, switching to GrizzlyClientContainer instead of JdkClientContainer or using a ws:// URL works. Tested using Tyrus version 1.15.
