Our latest release of the T.O.V.A. 9 (9.0-78) uses Java 8 (8u111 on Windows, 8u102 on Mac). Our latest release of the T.O.V.A. 8 (8.2-202) uses Java 8 (8u45) on Windows, Java 7 (7u71) on Mac.
The T.O.V.A. copies the Java we use locally, so that you no longer need Java "installed" to run the T.O.V.A. Because this is not an "installed" Java, it will not run in your browser or with any other application, so it should not pose any security risk.
If you have upgraded to 8.2 from an earlier version of the T.O.V.A., you can uninstall Java 6 (or any other version). Please note that your PC may have other software installed that relies on Java, and uninstalling it could affect that software. If you do uninstall Java 6, please do so with caution.
Bear in mind that Java is updated regularly (usually every few months), but the T.O.V.A.'s local copy will not be. Since we may not always have tested the T.O.V.A. with the latest Java release, a static copy insures that the T.O.V.A. will continue to run even when your installed Java is updated. If you have concerns and want to run the T.O.V.A. with the latest release of Java, please contact us for instructions or assistance.
