When using resteasy client to connect to other system form stateless bean I have (sometimes!) following stack trace (see bellow):

public PlaceImageResource getPlaceImageResource()

{ RegisterBuiltin.register(ResteasyProviderFactory.getInstance()); return ProxyFactory.create(PlaceImageResource.class, getResourceInterfaceUrl()); }

Frequency of reproducibility of this problem indicate that it is some concurrency problem e.g. racing condition:
