docs: Gets the value of a named configuration parameter. Same as
  getParameter(String name) but prepends the location of FEDORA_HOME if
  asAbsolutePath is true and the parameter location does not already
  specify an absolute pathname.
  
  @param name
  The parameter name.
  @param asAbsolutePath
  Whether to return the parameter value as an absolute path relative
  to FEDORA_HOME.
  @return The value, null if undefined.
