    Description

      On GlassFish 6.1.0-SNAPSHOT under JDK 11, which uses Weld 4.0.0.Final, deploying something as minimal as a .jar with only a single EJB and an interface in it, results in the following exception:

      Moving the EJB and its interface to a package solves the problem, but this still seems like a regression. On GlassFish 6.0.0 using Weld 4.0.0.Final as well, but running on JDK 8 the exception did not seem to happen.
