 * location of server www root on file system (see test.server.dir java property),
 * stubs for launching javaws and for locating resources and read resources.

 * It can also execute processes with timeout (@see PROCESS_TIMEOUT) (used during launching javaws)
 * Some protected apis are exported because public classes in this package are put to be tested by makefile.
