My apologies, I didn't notice your attachment until I had already hit send.
Checking the list shows that gwt-materialdesign is bringing in an old
version of htmlunit (GWT 2.10.0 updated this also), which is in turn
bringing in some old jetty versions:
| | \--- org.eclipse.jetty.websocket:websocket-client:9.2.18.v20160721
| | +--- org.eclipse.jetty:jetty-util:9.2.18.v20160721
*| | +--- org.eclipse.jetty:jetty-io:9.2.18.v20160721*
I can't speak to how your Gradle setup is configured, but I think you
should have an explicit compile dependency on gwt-dev:2.10.0, which should
at least force jetty-io and htmlunit to be updated to the expected versions.
