New Revision: 1852106
URL: http://svn.apache.org/viewvc?rev=1852106&view=rev
Log:
When running under a SecurityManager, ensure that the ServiceLoader look-up for
the default javax.websocket.server.ServerEndpointConfig.Configurator
implementation completes correctly rather than silently using the hard-coded
fall-back.
