Which Java versions does JPedal support?

Compatible Versions

JPedal is compatible with Java 8 and later versions of the language.

The minimum compatible version will be Java 8 until at least October 2024. We are strongly considering raising this to Java 11 in Oct 2024 and will confirm our plans in October 2023.

JPedal 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.

A note about OpenJDK 8:

Whilst we support Java 8, due to bugs in the OpenJDK 8 JVM implementation, running JPedal with OpenJDK 8 can cause lower-quality rendering, missing image content, higher memory usage, and potentially JVM crashes.

If you are currently running JPedal using OpenJDK 8 we strongly recommend you update to at least OpenJDK 11 or use an alternative JDK provider.

Supported Versions

We offer support for running JPedal on Java 8, Java 11, Java 17, and the latest Java version.

This policy will be reviewed in October 2023. We will give at least 12 months notice of removing Java 8 support.
