i changed TransactionContext.getResourceManagerId to also append the
connections clientid
private String getResourceManagerId() throws JMSException {
return this.connection.getResourceManagerId() + "/" +
this.connection.getClientID();
}
therefor isSameRM() now only returns true for xaresources based on the same
amq-connection.
now everything works as expected, but don't know if this would be a valid
approach (or even the right place) to fix this :)
