Resolution: Fixed
> An early query of 'org.apache.qpid.dispatch.router.node' can crash the router

> Analysis:
> The query is causing a qdr_address_t entry for
> amqp:/_topo/0/<router>/qdrouterd to be added to the routing table with
> treatment QD_TREATMENT_ANYCAST_BALANCED. Control messages must not use this
> treatment and the assert tests for it.
> Hypothesis:
> The query causes the 'R<router>' to be looked up before the other router has
> been established. This causes a new address entry with the default treatment
> to be created.
