Summary

Applets are obsolete, and the javax.naming.Context.APPLET constant has been deprecated for removal since Java 9.

The time has come to remove this constant.

Problem

JNDI dependency on the java.applet.Applet has been removed in JDK9 with JDK-8051422. It made the Context.APPLET environment property obsolete and to be ignored when javax.naming.InitialContext is created.

The javax.naming.Context.APPLET constant can now be removed.

Solution

Remove the APPLET constant from the javax.naming.Context class.
