agree, this is a problem. I think we can remove the dependency on geronimo-jta_1.0.1B_spec from activemq-core altogether, need to do a build to validate. in any event, as it is already an optional dependency, there is no good reason to include it in activemq-all. can you raise a jira to track this.
