[Users] Fedora 18 and jboss-as update

Hello, having all-in-one 3.2.1 based on f18 I'm now proposed an update of jboss to version 7.1.1-17.fc18 Some time ago I remember someone writing about problems with jboss updates but I don't remember if with nightly or in general... Currently I have jboss-as-7.1.1-13.fc18.noarch Can I safely update it? The same for not all-in-one installations? anyone already updated ? Thanks in advance, Gianluca
