For anyone else encountering this problem, this is a temporary workaround until this gets fixed in the Git repo:
- Add Guava 12.0 as a managed dependency in the POM. This is a workaround for bug 870349.
- Also add an exclusion for weld-servlet-core, to the errai-weld-integration artifact, like so:
org.jboss.errai errai-weld-integration weld-servlet org.jboss.weld.servlet weld-servlet-core org.jboss.weld.servlet
