Summary

Remove the outdated and unmaintained demos and samples.

Non-Goals

It is not a goal to create new or replacement demos and samples.

Motivation

Most of the existing demos and samples in jdk/src/demo andjdk/src/sample are out of date and unmaintained, and thus no longer useful either to developers working on the JDK itself or to the broader Java community. Their source code no longer represents state-of-the-art usage of the Java programming language and the Java SE Platform, and there are no plans to update them. Better sample code is available from many other sources, for example in the many articles, books, and presentations published in the broader community.

Description

A few demos are used for testing, and thus will be moved to an appropriate location in the test hierarchy of the jdk repository:

demo/share/applets
demo/share/java2d
demo/share/jfc

The remaining demos and samples will be removed from the jdkrepository:

demo/share/jvmti
demo/share/management
demo/share/nbproject
demo/share/scripting
demo/solaris/jni
sample/share/annotations
sample/share/forkjoin
sample/share/jmx
sample/share/lambda
sample/share/nio
sample/share/scripting
sample/share/try-with-resources
sample/share/vm
sample/solaris/dtrace

Corresponding makefile changes will be made. Built JDK images will no longer contain demo or sample directories.

Alternatives

If there is strong demand then the source to be removed could be published in a separate repository outside of any JDK Release Project, though in any case it will always be available in the Mercurial history of the jdk repository.
