Reproduce the issue in Apache NetBeans 24 on Ubuntu with the FlatLaf Cupertino dark theme, a breakpoint on an expression containing a method call, and the debugger paused there. Start by tracing the Java editor debugger highlighting and color settings; done means the active method display is readable in dark themes and the relevant setting is identifiable.
