Java Module java.desktop Package javax.swing Interface UIClientPropertyKey（JDK11）

public interface UIClientPropertyKey

This interface is used only for tagging keys for client properties for JComponent set by UI which needs to be cleared on L&F change and serialization.

All such keys are removed from client properties in JComponent.setUI() method after uninstalling old UI and before installing the new one. They are also removed prior to serialization.
