[GSS](7.2.z) "WFLYSRV0003: Could not index class ..." happens during application deployment when the packaged library contains module-info.class

XMLWordPrintable

      "WFLYSRV0003: Could not index class ..." happens during the application deployment when the packaged library contains module-info.class.

      For example, module-info.class is included in log4j2 since 2.10.0 or later. So, when an application uses and packages the latest log4j2, the following WARN message is logged at the deployment:

      WARN  [org.jboss.as.server.deployment] (MSC service thread 1-5) WFLYSRV0003: Could not index class META-INF/versions/9/module-info.class at /content/example.war/WEB-INF/lib/log4j-api-2.11.1.jar: java.lang.IllegalStateException: Unknown tag! pos=4 poolCount = 32

	at java.lang.Thread.run(Thread.java:748)

      I think this is not harmful, but it's better to suppress this WARN log.

      This is the same issue to JANDEX-40 which was already fixed in jandex 2.0.4.Final or later. (JANDEX-41 is also related, but EAP 7.1 does not support JDK 9+. So, JANDEX-40 is enough for EAP 7.1.z.)

      Please upgrade jandex to 2.0.4.Final or later (2.0.5.Final would be better as it's the latest at this moment).
