Red Hat build of OpenJDK new features and enhancements

Review the following release notes to understand new features and feature enhancements that Red Hat build of OpenJDK 8.0.442 provides:

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
Note

In Red Hat build of OpenJDK 8.0.442, the jar tool retains the old behavior by default. If you do not explicitly specify the ‑k option, the jar tool automatically overwrites any existing files with the same name. 

See JDK-8335912 (JDK Bug System) and JDK bug system reference ID: JDK-8337499.
