    Description

      When starting up my endpoint such that the JAXB classes referenced from the endpoints do not exist in the War project, but rather in a separate project on the classpath a strange issue occurs. Essentially the loop within JAXBUtils.scanPackages that loops over the "classes" Set will get a "null" Class from the set.

      Attached is:
      1) sample project
      2) screen shot of the missing class element during a debug session
      3) dump of a conditional breakpoint which logs the class name of the class within the loop until the class is null.
      4) a possible patch to workaround the problem

      To run the project and reproduce the problem:
      1) unzip the attached project file
      2) change directories to the Pom project, execute mvn clean install
      3) change directories to the War project, execute mvn jetty:run
      4) you should see a stacktrace similar to this:

      The patch which is attached might just mask the real underlying problem. I'm not sure if the problem is because the Set is being modified as its being iterated over. I certainly couldn't find a place where that was happening, but who knows.
