    Description

      The CatalogFactory#getInstance() is using thread context ClassLoader which gives undefined behavior under OSGi.

      This leads to problems with ConfigCatalogRule and especially LookupCommand.

      Two bundles wired to same commons chain may use different catalog factories when parsing commands from XML or looking up commands from catalog.

      I think that CatalogFactory#getClassLoader() might allow disabling use of thread context class loader - either

      a) detect that it is used inside OSGi framework, or
      b) provide static boolean flag to disable it

      Combination of both might be via use of bundle activator that would set the flag. The activator would be used only under OSGi acting as "auto-detection" and still some other bundle might revert to default if required.
