Description

Simple scenario: A component references (statically, 1:1, look-up strategy) a service. When the bundle providing that service is stopped and hence the reference no longer satisfied, stopping the bundle providing the component will result in the below exception.

I checked with Equinox 3.4.1 and there everything is working fine.

ERROR: net.eclipsetraining.backoffice.tplan.app.swing (9): [net.eclipsetraining.backoffice.tplan.ui.swing.internal.Component] BundleComponentActivator : Exception invalidating
java.lang.IllegalStateException: The service registration is no longer valid.
