> API specification says about BasicTextAreaUI.create "Returns a WrappedPlainView or PlainView". 
> But for [bidi](https://github.com/openjdk/jdk/blob/d14e96d9701dae951aa365029f58afb6687a646a/src/java.desktop/share/classes/javax/swing/plaf/basic/BasicTextAreaUI.java#L168) text, this method returns BoxView and other views , so the documentation needs to be updated.
