The internal package `com.sun.net.ssl` has been removed from the JDK. Prior to Java SE 1.4, when JSSE was shipped as a standalone product, the `com.sun.net.ssl` APIs were supported, but since Java SE 1.4, the package was deprecated and intended for internal use only. Standard replacement APIs such as `HostNameVerifier`, `KeyManager`, and `TrustManager` have been available in the `javax.net.ssl` package since Java SE 1.4. Although applications should have transitioned to the standard APIs, this note is a final warning that these non-standard APIs have been removed.
