COPPER has been upgraded to ASM 6.1, so Java 9, 10 and 11 are now supported in addition to Java 8. This release no longer supports Java 7 or older versions.
COPPER 5.0 adds support for the Java Platform Module System in order to let you build modular applications. However, if you don’t need this feature, you can use COPPER the same way as before.
Another addition to this release is a demo project showing how to build a modular application with Java 11 and COPPER 5. It provides a Gradle script for creating a custom runtime image of this application.
