RCP application no longer able to update after migrating to Helios [message #544195]

With the help of some black magic I had managed to get an RCP application to use a p2 repository to check for updates.

Unfortunately the setup no longer works after migrating from Eclipse 3.5 to 3.6. The headless build still has generate.p2.metadata set=true and appears to populate the repository and create the same p2 directory etc within the product.

But when I start the RCP application, I am warned that "the update checker service is not initialized", and when I run a "Check for Updates..." I get: "Could not locate the running profile instance. The eclipse.p2.data.area and eclipse.p2.profile properties may not be set correctly in this application's config.ini file." The config.ini file is almost identical to the previous one (other than some version numbers).

Didn't touch the configuration when I upgraded, though I did have to remove two plugins that no longer exist from the product definition (org.eclipse.equinox.p2.exemplarysetup and org.eclipse.core.resources.compatibility) and add a bunch (looks like org.eclipse.equinox.p2.ui.sdk now depends on org.eclipse.compare which depends on org.eclipse.ui.editors which depends on a dozen other plugins...).

Did anyone else encounter a similar problem?

and:

So something isn't quite right, but what?
