Can anyone translate this lengthy error in to plain English?

I'm trying to install a war file into Glassfish 4 using the admin interface. The project was built with the Google Web Toolkit, and if it makes any difference, the IDE I'm using is Eclipse-Kepler built using Eclipse IDE. I do not understand the getting an error that I do not understand the error I'm getting while trying to install the application. Below is the error that appears in the raw log:

[2014-05-22T22:12:15.568-0700] [glassfish 4.0] [SEVERE] [] [javax.enterprise.system.core] [tid: _ThreadID=128 _ThreadName=admin-listener(7)] [timeMillis: 1400821935568] [levelValue: 1000] [[ Exception while loading the app : CDI deployment failure:WELD-001408 Unsatisfied dependencies for type [Set] with qualifiers [@Default] at injection point [[BackedAnnotatedParameter] Parameter 1 of [BackedAnnotatedConstructor] @Inject com.google.gwt.thirdparty.guava.common.util.concurrent.ServiceManager(Set)]

As you can well imagine, I can't even begin to fix the problem if I don't even understand the error (and why is org.jboss in the error. I don't even have any jboss tools installed in Eclipse).

Can anyone translate that error for me?
