[platform-update-dev] Correct way to check if a feature is installed

["Andrew Sandstrom" <Andrew_Sandstrom@xxxxxxx>]

Sorry if I'm asking a dumb question, but what is the recommended way of
finding out if a feature is installed? I got the following from somebody,
but when I try this in a runtime workbench in PDE , the getLocalSite() call
takes forever to run, and just prints a bunch of "unzip complete" messages.

SiteManager.getLocalSite().getCurrentConfiguration().getConfiguredSites
().getSite().getFeatureReferences()

Thanks
