With addInstance the exception is: java.lang.IllegalStateException: Construction of service 'ServiceOverride' has failed due to recursion: the service depends on itself in some way. Please check org.apache.tapestry5.ioc.internal.services.ServiceOverrideImpl(Map) (at ServiceOverrideImpl.java:31) via org.apache.tapestry5.ioc.services.TapestryIOCModule.bind(ServiceBinder) (at TapestryIOCModule.java:49) for references to another service that is itself dependent on service 'ServiceOverride'.
