Hmm, probably yes because in `JComponent.setComponentOrientation()` spec it says "_To set the orientation of a single component, use this method. To set the orientation of an entire component hierarchy, use [applyComponentOrientation](https://docs.oracle.com/en/java/javase/22/docs/api/java.desktop/java/awt/Component.html#applyComponentOrientation(java.awt.ComponentOrientation))._".
