Jbas015852 Failed to index class java.lang.IllegalStateException: Unknown tag

Question

This error occurs when deploying to a local JBOSS server. Is there any way to resolve this warning?

An explanation of what is happening would also be appreciated.

Answer 1

I am 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 replaced "jandex-1.0.3.Final-redhat-2.jar" with "jandex-1.2.2.Final-redhat-1.jar" in JBoss modules and the problem was solved.

JBoss has a problem, possibly problems with Java 8 or lambda expressions that Jandex cannot index. See Link. This is a bug link for bug 1193113. I hope this helps you.
