Release Note: The system property sun.zip.disableMemoryMapping has been removed

XMLWordPrintable

      The zip library implementation has been improved in JDK 9. The new java.util.zip.ZipFile implementation does not use **mmap** to map ZIP file central directory into memory anymore. As a result, the `sun.zip.disableMemoryMapping` system property is no longer needed and has been removed.
