When redeploying a @Service (that had previously failed during start()):

Caused by: org.jboss.ejb3.common.registrar.spi.DuplicateBindException: Cannot install org.jboss.ejb3.proxy.impl.factory.session.service.ServiceRemoteProxyFactory@4cc4ee24 under name "ProxyFactory/ejbthree1738/RunAsService/RunAs/remote" as there is already an existing object there: org.jboss.ejb3.proxy.impl.factory.session.service.ServiceRemoteProxyFactory@4c6cb02a

Note that an explicit jndiBinding has been provided.
