Description

This JavaFX program runs fine on Java 8:

//@CompileStatic
class ImageCompStatic
{
  public static void main(String[] args)
  {
    PlatformImpl.startup({})   // quick hack to start up the JavaFX runtime
    String path = "image.png"
    Image img = new Image("$path")
    println img.height
  }
}

If CompileStatic is not commented out, you get the following error at run time:
Exception in thread "main" java.lang.IllegalAccessError: tried to access method javafx.scene.image.Image.<init>(Ljava/lang/Object;)V from class ImageCompStatic

CompileStatic seems to change the selected constructor from the correct one:

public Image(String)

to the wrong one:

private Image(Object)

Changing the constructor invocation to:

    Image img = new Image("$path" as String)

also works.
