Description

There is now a Manifest editor warning if a non-optional dependency has a higher BREE. This triggers for at least org.eclipse.uml.common.edit and org.eclipse.uml.edit that neglect to make org.eclipse.core.runtime/org.eclipse.core.resources optional. This is inconsistent with org.eclipse.emf.edit. It ripples to cause warnings in org.eclipse.ocl.uml.edit.

Please make the dependencies optional.
