[…] 

Caused by: java.lang.IncompatibleClassChangeError: Found interface com.google.gwt.core.ext.typeinfo.JClassType, but class was expected

In GWT 2.2, JClassType (everything in com.google.gwt.core.ext.typeinfo actually) was changed from an interface to an abstract class (that was almost 6 years ago already, and I can't find where it was announced; and release notes for such ancient versions have been lost)

at com.extjs.gxt.ui.rebind.core.TemplatesGenerator$SourceGenerator.validateType(TemplatesGenerator.java:142)

You need to update GXT (and all your other dependencies) to a version that's compatible with GWT 2.7.
