 *
 * This class provides access to virtual server and stuff around.
 * It can find unoccupied port, start server, provides its singleton instantiation, lunch parallel instantiations,
 * read location of installed (tested javaws) see javaws.build.bin java property,
 * location of server www root on file system (see test.server.dir java property),
 * stubs for lunching javaws and for locating resources and read resources.
 *
 * It can also execute processes with timeout (@see PROCESS_TIMEOUT) (used during lunching javaws)
 * Some protected apis are exported because public classes in this package are put to be tested by makefile.
 *
 * There are included test cases which show some basic usages.
