Description

The jboss-ec2-eap packages provide scripts for Red Hat JBoss Enterprise Application Platform running on the Amazon Web Services (AWS) Elastic Compute Cloud (EC2).

With this update, the jboss-ec2-eap package has been updated to ensure compatibility with Red Hat JBoss Enterprise Application Platform 6.4.15.
