We've just published JFormDesigner 7 Early Access 1 with:
- Java 9 support.
- New icon/image chooser dialog.
- Load images from project source folders.
- Icon editor: Support selecting icons in JARs of classpath.
- and more...
JFormDesigner 7 is in active development and not feature complete.
Besides working on new features, improvements and bug fixes, we've migrated the whole JFormDesigner source code to Java 8. Now using lambdas, method references, streams, etc.
As a consequence, if you're using a JFormDesigner IDE plug-in, your IDE now needs to run in a Java 8 (or 9) VM. That's one reason why we dropped support for older IDE versions. See new System Requirements.
