Eclipse The activator for bundle org.eclipse.equinox.ds is invalid

[biermann24]

Hallo zusammen,

ich versuche eine Eclipse RCP Applikation zu starten und scheitere mittlerweile immer mit folgender Exception:

!MESSAGE FrameworkEvent ERROR

Ich kann mir leider garkeinen Reim daraus machen, hoffe Ihr kennt euch besser aus 😉

Dein Code ist falsch 🙂

Deine normalen Activator sollten org.osgi.framework.BundleActivator implementieren.

Das ist garnicht mein Aktivator:

activator org.eclipse.equinox.internal.ds.Activator

Das eigentliche Problem schein ja auch das hier zu sein:

java.lang.ClassCastException: org.eclipse.equinox.internal.ds.Activator cannot be cast to org.osgi.framework.BundleActivator

[EDIT]
Wenn ich den Autostart für equinox.ds rausnehme scheitert es woanders:

java.lang.ClassCastException: org.eclipse.core.internal.runtime.Activator cannot be cast to org.osgi.framework.BundleActivator
