A Move For Red Hat's JBoss

Hitting the web today is word that Red Hat's JBoss is planning to move to a similar development model to Red Hat Enterprise Linux / Fedora (eWeek article). Starting this June, JBoss will have a bleeding-edge community edition of its software (similar to Fedora) while there will still be the stable and finely-tuned version of JBoss that comes after testing and stabilization from the free version (similar to the Red Hat Enterprise Linux path). No backward compatibility is guaranteed with the free edition. The new JBoss will have a publicly available source-code control system in addition to the binaries for the free Fedora-like version. This news is coming after last week's announcement of GlassFish, JDK 6, and Java DB 10.2 being available from Ubuntu's Multiverse repository. Will we soon be encountering a heated face-off between Sun Microsystems and Ubuntu against Red Hat and JBoss?
