FormVu is compatible with Java 8 and later versions of the language.
The minimum compatible version will be Java 8 until at least March 2021.
FormVu is a multi-release jar. It will run on Java 8 without module path and also supports the module path available in Java 11 and later.
Whilst we support Java 8, due to bugs in the OpenJDK 8 JVM implementation, running FormVu with OpenJDK 8 can cause lower-quality rendering, missing image content, higher memory usage, and potentially JVM crashes.
If you are currently running FormVu using OpenJDK 8 we strongly recommend you update to at least OpenJDK 11 or use an alternative JDK provider.
We offer support for running FormVu on Java 8, Java 11, and the latest Java version.
This policy will be reviewed in March 2021. We will give at least 12 months notice of removing Java 8 support.
