      Parameters:
        `providers` - list of ContainerProvider
      Returns:
        list of package providers
      Throws:
        `ConfigurationException` - in case of any configuration errors

    - #### createBootstrapContainer

          protected Container createBootstrapContainer(List<ContainerProvider> providers)

    - #### buildRuntimeConfiguration

          protected RuntimeConfiguration buildRuntimeConfiguration()
                                                            throws ConfigurationException

      This builds the internal runtime configuration used by Xwork for finding and configuring Actions from the programmatic configuration data structures. All of the old runtime configuration will be discarded and rebuilt.

      It basically flattens the data structures to make the information easier to access. It will take an `ActionConfig` and combine its data with all inherited dast. For example, if the `ActionConfig` is in a package that contains a global result and it also contains a result, the resulting `ActionConfig` will have two results.

      Returns:
        runtime configuration
      Throws:
        `ConfigurationException` - in case of any configuration errors
