As a result of JDK-8051422 using of javax.naming.Context.APPLET will be deprecated. This constant is used in the com.sun.jndi.toolkit.corba.CorbaUtils class. It looks like CorbaUtils is piggybacking on the jndi-applet parameters reading mechanism. There must be a different way to initialize ORB with parameters specified in an applet.
