JBoss instance A hosts application A which has a context root of /abc.
JBoss instance B hosts application B which has a context root of /abc/xyz
A and B are not in the same cluster.
The behavior is the requests meant for application B are getting routed to application A on JBoss instance A and the result is an http error 404. A request to /abc/xyz/my.jsp should correctly go to application B on JBoss instance B.
