However, "NSComboBox, because of its direct affinity to NSTextField, has the square bezel corners" rather than "the softer rounded corners that the button family uses". My understanding from this is, since JComboBox relies on TextField, it uses the native TextField's square corners. ------------- PR: https://git.openjdk.org/jdk/pull/12750
