RHQ 4.9 and later will use EAP 6.1.0.Alpha1, for the reasons you mentioned. Even if it's labeled *Alpha* it's stable (and should be more stable than 7.2 Final).
If your company policy requires you to deploy only final EAP versions then consider subscribing to JON which will use EAP 6.1.0.Final.
Hello Thomas -
No policy - just curious
And subs is in the works but I like the cutting edge of RHQ, JON is lacking a bit behind at the moment.
