With JMS there are some configurations where the jndi name is not guaranteed to be unique so when diagnosing recovery issues just reporting this jndi name is insufficient for identifying which server created the XID that is being recovered.

We can resolve this issue by providing a unique id that identifies the resource manager that created the XID. The proposal is to add this id to the transactions SPI (specifically to the org.jboss.tm.XAResourceWrapper interface)
