Expected Behavior
Calling CodeArea.replaceText() should replace the contents of the CodeArea without throwing any exception.
Actual Behavior
When the CodeArea contains multiple lines, calling CodeArea.replaceText() triggers an exception, show below:
Button pressed

Reproducible Demo
Run this, then press the button twice.
Use the following template to get started.
public class App extends Application {
CodeArea codeArea;
Button button;
public static void main(String[] args) {
launch();
}
@Override
public void start(Stage primaryStage) throws Exception {
codeArea = new CodeArea();
codeArea.setParagraphGraphicFactory(LineNumberFactory.get(codeArea));
codeArea.setWrapText(false);
button = new Button("Press me Twice");
button.setOnAction(actionEvent -> {
actionEvent.consume();
System.out.println("Button pressed");
codeArea.clear();
// Doesn't really matter what is inside codeArea text,
// As long as it span multiple lines, the exception is thrown
codeArea.appendText("Lorem ipsum\n");
// If you remove the \n from above it won't throw an exception anymore
codeArea.replaceText(String.valueOf(Math.random()));
});
Parent root = new StackPane(codeArea, button);
primaryStage.setScene(new Scene(root));
primaryStage.show();
}

- RichTextFX Version: 0.10.6 from Maven
- Operating System: Windows 21H1 and ArchLinux
- Java version: 16.0.1 (Microsoft and ArchLinux's OpenJDK builds)
As this bug is reproducible on multiple OSes and JDK builds, I don't think this is platform dependent.
