A DESCRIPTION OF THE PROBLEM :
AquaLookAndFeel does not properly move the drop-down button for JComboBox when the component orientation is changed (specifically, when the component orientation is changed from LEFT_TO_RIGHT to RIGHT_TO_LEFT). This means that text may be covered up by the drop-down button, especially if the editor component also has its component orientation updated.

MetalLaF: https://github.com/openjdk/jdk/blob/master/src/java.desktop/share/classes/javax/swing/plaf/metal/MetalComboBoxButton.java#L183
AquaLaF: https://github.com/openjdk/jdk/blob/master/src/java.desktop/macosx/classes/com/apple/laf/AquaComboBoxButton.java#L98

It looks like Aqua LaF is not handling changing component orientations for the combobox button.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Using the attached source code, toggle left-to-right using the button "Toggle LTR".

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The drop-down button for the AquaLookAndFeel behaves similarly to that for MetalLookAndFeel (as in, it moves to the left side of the combobox).
ACTUAL -
The drop-down button for the combobox does not move, and blocks visibility for text in the text field.

CUSTOMER SUBMITTED WORKAROUND :
Use a different LookAndFeel like Metal.
