I guess those might be null at class initialisation stage so it didn't render..you can try expandedIconWrapper = new IconWrapper(expandedIcon); collapsedIconWrappr - new IconWrapper(collapsedICon); in updateStyle() where it sets setExpandedIcon(style.getIcon(context, "Tree.expandedIcon")); setCollapsedIcon(style.getIcon(context, "Tree.collapsedIcon")); ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/17294#discussion_r1447325540
