Description Boris Bokowski

Probably happens because in org.eclipse.pde.internal.ui.wizards.product.ProductFromExtensionOperation.getPlugins() the HashMap fDependencies of DependencyCalculator never gets initialized properly.

To reproduce this NPE you need to have a product that has a different prefix than the bundle that defines it.  We should look at ways to improve the error messages when a plug-in cannot be found.  Listing the exact product id and which bundle name we are looking in would be a good start.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
