Netweaver Development Infrastructure (NWDI) vs Team Foundation Server (TFS) vs ?

Hi all,
i'm currently learning SAP NWDI. SAP NWDI is a tool provided by SAP with the goal of providing a platform and a model for simplifying development.

When i first started looking at NWDI, my first question was:
Why do we need this when we have:

-SCM tools like SVN, CVS, GIT, VSS, Perforce, Bazaar for source control.
-MAVEN, ANT, NANT and others for building, deployment and automation purposes.
-Continuum, jUnit, nUnit, CruiseControl for continuum developement and tests.
-Eclipse,Visual Studio and many others IDE.
-Bugtrackers like Bugzilla,JIRA and others.

Well, with time passing i've started to see the light here.

Tools such as NWDI for SAP Java Development and TFS for .NET Development are intended to integrate some of these concepts into a model of development. This model provides best practises and a unified method of development.
I know that in IT area we need to continually evolve but software development needs stability. We need a model in which we can rely and covers all the needs of the market independently from the techonology used.

I don't know any tool on JAVA to integrate the tools i've talked above in the same way as NWDI or TFS. Do you know any?
