Answer 6

Don't know the reason. But this works for me, so posting it.

Right-click on the project -> 'Properties' -> 'Java Build Path'

Answer 7

If you are using an osgi run configuration, Run -> Run Configurations... Select you laucher and click on the Bundles tab. Filter with org.eclipse.swt and make sure that the org.eclipse.swt and org.eclipse.swt.[arch].[version].jar are checked.

This drove me nuts until I did this simple thing. If you validate bundles without having checked these you'll get a "No Problems" dialog but you'll get this error at run time
