I'm using JBoss EAP 6.3 with patch 6.3.3 but to solve the problem I need to use jandex from JBoss EAP 6.4. I just replace "jandex-1.0.3.Final-redhat-2.jar" for "jandex-1.2.2.Final-redhat-1.jar" in JBoss modules and problem was solved.

There is a issue in JBoss of it, maybe problems with Java 8 or lambda expressions that Jandex can´t index. See this link This is the link of the issue Bug 1193113 I hope that help you
