Re: [p2-dev] Self-Hosting p2 and PDE SelfHostingProfile

Hi Gunnar, 

The problem is likely caused by the absence of os / ws / arch properties in the profile. To confirm this, look into the details of the command line argument being effectively passed to the VM (debug view, right click on the process), find the profile and see if you can find a property similar to this (<property name='org.eclipse.equinox.p2.environments' value=',osgi.arch=x86_64,osgi.os=macosx'/>)

Should this be the problem, your only way to continue testing your selfhosting is to first completely export your application (p2 enabled), then change your launch config to disable PDE selfhosting ability and set the following VM Args:<fileURLTop2FolderOfExportedApp>
