Title: About Java Transactions API (JTA) There is a sentence "JTA transactions are not distributed across multiple application servers, and cannot be nested". It would be fine to mention that the JTA api specification does not supports distributed transactions but JBoss supports such thing. In the way that distributed means that more EAP servers could be involved in one transaction.
Because of https://bugzilla.redhat.com/show_bug.cgi?id=1018851 all changes are done in chapter "11.2.11. About Distributed Transactions" and it is phrased as: "Java Transaction Service (JTS) specification mandates that JTS transactions be able to be distributed across application servers from different vendors (transaction distribution among servers from different vendors is not a supported feature). Java Transaction API (JTA) does not define that but JBoss EAP 6 supports distributed JTA transactions among JBoss EAP6 servers." Verified on Revision 6.3.0-31
