Alpha2-SNAPSHOT has been "released" and Alpha3 is now where we are at. Going back in version just to clean up this mistake is going to be more confusing.
What do you mean by released? Alpha2-SNAPSHOT, by definition, has not been released in my understanding.
AFAICS, the Alpha1 bits of JBT now reference TP 4.30.5.Alpha. http://download.jboss.org/jbosstools/updates/kepler/compositeContent.xml
It would have been confusing is 4.30.5.Alpha3-SNAPSHOT had been used widely by the team, but I don't think it happened.
