Dear customers,
Although Java 9 released on September 2017, many of our underlying technologies (Android SDK, Jetty, iText, POI, Batik, and so on) do not yet support Java 9.
As such, Genero 3.10 does not support Java 9.
We will continue to monitor the community and work to provide Java 9 support ASAP.
Best regards,
Four Js Support
