Build Identifier: 

Some eclipse functionality depends on the simpleconfigurator to discover information about the host platform. Any such functionality breaks when running JUnit plugin tests with tycho.

For example, I have some JUnit plugin tests that 
  - create a test projects in the runtime workspace
  - add a JUnit libraries classpath container to the test project
  
These test project don't work/compile correctly in the runtime workspace when running inside tycho because the JUnit libraries classpath container doesn't correctly resolve. Thus the projects will be missing JUnit libraries and fail to compile.

With some digging I discovered that the reason why Junit classpath container is not resolving correctly is because the org.eclipse.junit.core plugin relies on 
bundles.info file to discover the installed junit bundles and find the junit jar files in them. 

It does this by calling on functionality from org.eclipse.equinox.simpleconfigurator.manipulator.SimpleConfiguratorManipulator

Relevant code lives in org.eclipse.jdt.internal.junit.buildpath.P2Utils
in the ..eclipse.jdt.junit.core bundle. (E.g. see the 'findBundle' method).

Reproducible: Always

Steps to Reproduce:
1. Import attached plugin project as an 'existing project' into Eclipse RCP
2. Run as Junit plugin test => test passes
3. Create a tycho build that runs the same test suite.
4. The test will fail.
