Testing records on the JavaFX source, I created this branch on GitHub: https://github.com/nlisker/jfx/tree/Records

Running `./gradlew` to build throws the compilation exception:

An exception has occurred in the compiler (14). Please file a bug against the Java compiler via the Java bug reporting page (http://bugreport.java.com) after checking the Bug Database (http://bugs.java.com) for duplicates. Include your program, the following diagnostic, and the parameters passed to the Java compiler in your report. Thank you.

Attached the .args file.

I suspect that the issue has to do with the @NamedArg annotations on the record components, such as in the javafx/scene/web/PopupFeatures.java class.
