Error while starting JBoss - Could not read provided index: /content/<<warFile>>r/WEB-INF/lib/camel-api-3.0.1.jar/META-INF/jandex.idx

I got the same issue with JBOSS EAP 7.2.3. To quickly test a newer JBOSS EAP version I installed the current wildfly version (wildfly-20.0.1.Final). With it the problem is solved. So, updating to a JBOSS EAP 7.3.0 or newer will solve this problem.
