Widgetset compilation failed
I have not seen this before - it looks like a classpath problem, or maybe the widget map generator is not invoked correctly when performing GWT compilation. I assume you have not tweaked anything related to Vaadin or GWT in your project classpath settings, but that is good to check.
Try to change to another Vaadin version in Project Properties → Vaadin and then recompile - changing it from there should also update GWT references unless you have modified them yourself in the project classpath. If that works, then change back to 6.4.8 and recompile again.
I am curious, I notices some client configurations inherit
com.vaadin.terminal.gwt.DefaultWidgetSet , while others inherit
com.vaadin.DefaultWidgetSet .
Are those modules different?
Is it possible I have inconsitent client code in place due to having both modules included by different widgetsets?
com.vaadin.terminal.gwt.client.DefaultWidgetSet is the old location from Vaadin 6, com.vaadin.DefaultWidgetSet is the new location in Vaadin 7.
However, Vaadin 7 still includes a legacy c.v.t.g.c.DWS that does nothing but import c.v.DWS to make migration easier.
Sometime in the future (Vaadin 8 or later), c.v.t.g.c.DWS might get removed so best update to use c.v.DWS.

Tried different version 8.8.6 still the same problem.
