In the following class:

class Test {
var publicProperty = 0;
val readonlyProperty = 1;
}

1) publicProperty is a public property, but appears as private in the Outline view (the icon is a red box instead of green circle)
2) readonlyProperty has a volatile overlay in its icon (green letter v in top right corner of icon), which is incorrect, it should have an F in its overlay, which would be consistent with the overlay for final fields in Java.
