This looks like a classpath issue, from which I have suffered in the past but eventually managed to control.
I suggest using Maven dependency control to force the correct implementation of the offending classes, particularly if you are running with "GWT Eclipse Plugin" which doesn't respect inherited Maven dependency exclusions/overrides etc. If you are using "GWT Eclipse Plugin", even though it is becoming outdated, there is still a way to control the classpath. study https://github.com/eliasbalasis/eclipse-gwt-recipe for single-classpath for "Single CLASSPATH stream" traces. I hope this helps you.
