Problems with CDI Builder and scanning Jars which support Java 9

As reported in https://developer.jboss.org/message/978446?et=watches.email.thread#978446:

Setup:

• Eclipse Oxygen 4.7.1
• JBoss Tools 4.5.1.Final (also tested with latest development version 4.5.2.AM1)
• An maven web application with certain dependencies
  • So far, we found two dependencies, which lead to this jandex scaning error after upgrading to latest version
  • org.apache.logging.log4j version 2.10.0
  • org.ow2.asm version 6.0

This leads to an CDI Builder IllegalStateException - see exception trace below.
Both dependencies started support for Java 9, which seems to cause this exception.

Apache Log4j 2.10.0 released: http://mail-archives.apache.org/mod_mbox/www-announce/201711.mbox/%3Cdf950e3c-7ae2-6026-25c5-bfba671cfbbd%40apache.org%3E
