Release Note: JEP 398: Deprecate the Applet API for Removal - Closed
Description
Summary
-------

Deprecate the Applet API for removal.  It is essentially irrelevant since all web-browser vendors have either removed support for Java browser plug-ins or announced plans to do so.

History
-------

The Applet API was previously deprecated, though not for removal, by [JEP 289](https://openjdk.java.net/jeps/289) in Java 9.

Description
-----------

Deprecate, for removal, these classes and interfaces of the standard Java API:

  - `java.applet.Applet`
  - `java.applet.AppletStub`
  - `java.applet.AppletContext`
  - `java.applet.AudioClip`
  - `javax.swing.JApplet`
  - `java.beans.AppletInitializer`

Deprecate, for removal, any API elements that reference the above classes and interfaces, including methods and fields in:

 - `java.beans.Beans`
 - `javax.swing.RepaintManager`
 - `javax.naming.Context`

Testing
-------

Hundreds of tests need to be either modified or removed before the Applet API is removed, but this JEP is solely about deprecation-for-removal.  We will review these tests to determine if further `@SuppressWarnings` annotations are required.

Risks and Assumptions
---------------------

In case remaining uses of these APIs do exist, developers can suppress compiler warnings via the  `@SuppressWarnings("removal")` annotation or the `-Xlint:-removal` command-line option of the `javac` compiler.
Comments
This looks fine to me.

I’ve tightened this up and added a little more information about how to suppress the new warnings. Let me know if this looks okay to you and I’ll move it to Candidate.

Right. The JEP and eventual CSR should focus on public classes being deprecated for removal along with any impact on applications (not much impact, since this is just a deprecation JEP). The internal classes that are impacted are just part of the implementation of the JEP.

I don't see the need to mention internal classes in this JEP.

Yes - in EmbeddedFrame.java and Beans.java only selected methods (and in the Beans case two inner-classes) will be deprecated for removal.
10-11-2020
Ok so that method may be removed, but not the class.

EmbeddedFrame contains the public methods: public static Applet getAppletIfAncestorOf(Component comp) This method was deprecated when Applet was deprecated and I assumed it would be deprecated for removal when Applet is.

The following additional filesthat had @SuppressWarnings("deprecation") annotations need to be modified to SuppressWarning("removal"): src/java.desktop/share/classes/com/sun/java/swing/SwingUtilities3.java src/java.desktop/share/classes/com/sun/media/sound/JavaSoundAudioClip.java src/java.desktop/share/classes/java/awt/Component.java src/java.desktop/share/classes/javax/swing/JComponent.java src/java.desktop/share/classes/javax/swing/JTable.java src/java.desktop/share/classes/javax/swing/KeyboardManager.java src/java.desktop/share/classes/javax/swing/PopupFactory.java src/java.desktop/share/classes/javax/swing/RepaintManager.java src/java.desktop/share/classes/javax/swing/SwingUtilities.java src/java.desktop/share/classes/javax/swing/ToolTipManager.java src/java.desktop/share/classes/javax/swing/plaf/basic/BasicPopupMenuUI.java src/java.desktop/macosx/classes/com/apple/laf/AquaInternalFrameUI.java
