Although there was a problem with the interleaving property not being properly populated in terms of its managed property value, the current issue is that this is not an independent property. It can only be set to true for XA transaction type of factories. I don't know why this property shows up at a base piece of metadata rather than the XA capable subtypes. To properly resolved JBAS-6777 this needs to happen. Is there a reason why this should not be done? Similarly, the deprecated track-connection-by-tx also needs to be moved (or dropped) as it just delegates to the interleaving property.
