Most probably this isn't true. The tool is probably analysing the
dependencies using the Maven POM files for that. As a result it will
find that we require different versions of things because of the
transitive dependencies. But during runtime we use JBoss modules as our
class loading mechanism, and that strictly controls what libraries are
used, and we don't currently have two versions of the same module in any
case. Note however, that JBoss modules supports having multiple versions
of the same module, and doing that is justified and needed in some
cases, but we don't do it currently.

I checked the below libraries specifically, and I believe that there is
no duplication in our case.
