JDK 9 uses a new version string format. The most notable changes are the removal of the ���1.��� from the beginning of the version string and the use of 3 or more separate elements to specify major, minor, and security updates. All code that parses the value of the system properties `java.version`, `java.specification.version`, or `java.vm.specification.version` should be examined to ensure that it works with the new scheme. Maintainers of code that parses these properties should also be aware of the new `Runtime.version()` API. Details for the new version string format can be found in [JEP 223: New Version-String Scheme](http://openjdk.java.net/jeps/223).
