bundle has already installed error

[growing]

When I run the test case which was inherited from AbstractConfigurableBundleCreatorTests class, it always failed. I used spring framework and spring DM. The error information followed:

I really can't find out the reason. Anybody can help me? Please.

What version of Spring-DM are you using and how does your test look like? Try minimizing the test case since somebody is trying to install junit twice (either directly or indirectly by calling the method that causes the framework bundles install).
