Re: LogicalViewProvider.createLogicalView is called twice when project explorer is created. Why?

Cache the result of the first call.

Better yet, initialize as little as possible up-front (you can do
structural stuff on-demand when the node is expanded), but it's perfectly
fine to cache the result.  There's nothing in the API that guarantees that
it will only be called once.
