When I installed netbeans 7.3rc a few days ago, I selected to import the config from the previous release. My previous config for glassfish had some extra domains. The extra domains were deleted. I don't remember clearly, but I think the oracle driver was also deleted.

Well, I did not touch import utility since I took over this plugin so this may exist in older versions too. Please can you test it with 7.1/7.2 too?
I have some plans to rewrite it in the future but there is not enough time now (7.3/7.3.1).
