What is the Xmx value for the JVM that you use with
JBoss? I would imagine JBoss would require more than
the default JVM Xmx value
So could you try getting numbers by:
1. increasing the Xmx value in JBoss startup
2. getting separate timings for getSession() and
list() to identify where the difference really lies
