NPE during start of WebSocketServerFactory even after upgrading to eclipse.jetty-9.4.8.v20171121 #1143

Hello,

I was getting similar error mentioned in following link. https://github.com/perwendel/spark/issues/984

Tried the suggestions and still getting the same error. Upgraded to Spring boot version - 1.5.10.RELEASE which contains org.eclipse.jetty - 9.4.8.v20171121 version. No luck. Please help with this. Thanks
