Installation of free alternatives to Oracle JAVA

As of Java version 8.211 (2019-04-16), Oracle has introduced a license fee for commercial use of Java. Older Java versions remain free.

The functionality of the VAKA system is not affected by imposition of license fees or by the new Java version. More information about Java licenses is available at www.java.com..

For those who want to avoid licensing costs, the following options are recommended, for installation under Windows, MacOS and Linux, respectively.
