If I inject ServiceReference and BundleContext into a bean, and try to resolve it to a service interface at runtime using something like:

EchoService test = (EchoService) bundleContext.getService(serviceReference);

- it fails with the following error:

java.lang.ClassCastException: org.springframework.osgi.service.importer.support.ServiceReferenceDelegate
at org.eclipse.osgi.framework.internal.core.BundleContextImpl.getService(BundleContextImpl.java:890)
at b3.impl.ClientServiceImpl.getEchoService(ClientServiceImpl.java:33)
at b3.impl.ClientServiceImpl$1.run(ClientServiceImpl.java:23)

The problem is in the org.eclipse.osgi codebase, where it assumes that the incoming object will be their custom implementation..

class BundleContextImpl:
public Object getService(org.osgi.framework.ServiceReference reference) {
...
ServiceRegistrationImpl registration = ((ServiceReferenceImpl) reference).registration;
...
}
