With the latest Scala-Plugin the "Add unimplemented methods" Strg+1 doesn't work in .java files,
when I use it in Plugin-Projects. Steps to reproduce

1. Create plugin
2. Add plugin dependecy "org.osgi.util.tracker"
3. add this import to all examples below "import org.osgi.util.tracker.ServiceTrackerCustomizer;"

Now there are three types of this problem:

1. Anonymous class: With Strg+Space the methods appear, but don't get implemented, when clicked.
2. New Java-Class wizard, implement ServiceTrackerCustomizer => "Creation of element failed. Path for project must have only one segment"
3. Create a class FooCustomizer, add implements ServiceTrackerCustomizer, Strg+1 doesn't show "add unimplemented methods"

After I deinstalled Scala-IDE, everything worked fine. This error doesn't appear in normal scala-projects.
