Just to clarify in order to being able to determine the root cause.
We are currently registering the EventBusService as this:
public class AssetsRiskInformation extends
AbstractSingletonMultiTenantObjectRepositoryAndFactory<AssetRiskInformation> {
...
// {{ injected: EventBusService
private EventBusService eventBusService;
public final void injectEventBusService(final EventBusService
eventBusService) {
if (this.eventBusService == null) {
this.eventBusService = eventBusService;
eventBusService.register(this);
}
}
// }}
}
As seemed that the injectEventBusService(xxx) method was called more than once,
the register(this) must verify it's the first time.
Also, as seemed that the Service was "unregistered" by Isis when ending a
transaction, as per:

We are not sure if the service that the service is re-registered when starting
a new transaction:

Despite that, I think that this concurrency exception should be avoided:

On last page (22) of the following slideshare presentation [1], seems that once
injected, the safest way to register and unregister it is by means of the
@PostConstruct and @PreDestroy annotations, but not sure if that would
eliminate the exceptions thrown.
