Option for jar command to avoid overwriting files when extracting an archive

In earlier Red Hat build of OpenJDK releases, when the jar tool extracted files from an archive, the jar tool overwrote any existing files with the same name in the target directory.

Red Hat build of OpenJDK 8.0.442 adds a new ‑k option that you can use to ensure that the jar tool does not overwrite existing files.

For example:

jar xkf myfile.jar

jar xkf myfile.jar
