Plug-in Tools -> Organize MANIFEST.MF -> Remove unused dependencies leads to errors. You can test this for example with the org.eclipse.pde.ds.ui

Example compile errors after this clean-up:

cc @HannesWell as I think you recently work on this functionality

FYI - Also compile errors if I use the "Find unused dependencies" button in the manifest editor and remove the reported plug-ins

We are already working on this (and even in an automated way), beside that make sure to use latest i-build for such kind of tests as it requires bleeding edge JDT compiler to work.

I used yesterdays I-Build for the test

Can also be reproduced with "org.eclipse.tools.layout.spy" in:
