[news.eclipse.technology.equinox] Re: [P2] Remove plugins that are not i

[John Arthorne <eclipseng@xxxxxxxxxxxx>]

Simply upgrading from v1 to v2 in this case should be causing the unused 
feature to be uninstalled. Do you still see the feature listed under 
Help > About > Installation Details > Feature Details, or do you just 
see the old feature on disk. Garbage collection of uninstalled content 
doesn't happen immediately so you might just be seeing an uninstalled 
feature on disk that will eventually be garbage-collected automatically. 
If the feature is still really installed, perhaps there is some other 
feature that optionally references the experimental feature? If not, I 
suggest entering a bug against RT > Equinox > p2 with an example that 
illustrates the problem.
