JBoss AS 4.2.2.ga, JBM1.4.0.SP1.

I several clients that connect to a 2 machine cluster (devapp1 and devapp2).  Below is the JMSProvider I use.  On one machine I have the naming provider with devapp1 first in the list.  On the second I have devapp2, as shown here.  The second machine always connects to devapp1 unless I completely remove the reference to devapp1 from the list.  Then it it will connect to devapp2.  I thought it was supposed to try to connect in the order that they are listed in java.naming.provider.url.  Is this an incorrect assumption?  

I am able to determine which machine it has connection by looking at the number of consumers the app servers have connected to them.
