      When the server is started with -Djboss.server.base.dir, the property is configured twice for the server launch command.

      This is completely harmless for the server behaviour since the server can process the expected jboss.server.base.dir value even if it is duplicated in the launch command; hence, the resolution of this issue is minor.

      The only possible side effect is if a user application code is trying to read this property from the server environment and somehow it is not prepared to handle the read when this property is deuplicated.

      Fixing this will probably require detecting the condition in the standalone.sh script. Other scripts could be affected by the same issue.
