From talking to Brian, my understanding is that something in tools determines the ESB version by what version of jUDDI is in ESB. Since ESB 4.12 is including a new jUDDI (3.1.4), I'm not sure whether it will recognize a valid ESB installation with 4.12 as 4.11 or below.

Need to add ESB 4.12 option with constraints -------------------------------------------- Key: JBIDE-13209 URL: https://issues.jboss.org/browse/JBIDE-13209 Project: Tools (JBoss Tools) Issue Type: Task Components: esb Reporter: Tom Cunningham SOA-P 5.3.1 is coming out soon and will require an ESB "4.12" option to be added to the ESB versions. Additionally, it may or may not have a new jUDDI version, which would require a different constraint to verify the AS has ESB 4.12 - or a removal of the constraints altogether.
