For historical reasons we have always provided an uber jar for the various distributions of Narayana (local JTA, JacORB etc) which wraps up the content of the project into a single Jar.

With the advent of Maven this approach does not necessarily have the same importance as users can easily include the distribution by including a single dependency and its transitive dependencies.

From a development perspective it adds extra burden to maintain the uber jar poms and so I would propose to remove this facility in the next major release of Narayana (6).
