StackOverflowError

[DennisdeW]

I am using RichTextFX in my project, but I am having an issue which seems to be contained to Flowless:

I use the following code to append a certain message in bold font:

private InlineCssTextArea text;

//....
    //In constructor
    text = new InlineCssTextArea();
    text.setWrapText(true);
//....

public void appendBold(String msg) {
    Platform.runLater(() -> {
        int curPos = text.getText().length(); //The index of the first new character
        int endPos = msg.length() + curPos - 1; //The index of the last new character
        text.appendText(msg);
        text.setStyle(curPos, endPos, "-fx-font-weight: bold;");            
   });
}

(I have two other, similar methods for italic and normal fonts) This usually works, but sometimes it fails with a StackOverflowError, where the following section of stacktrace repeats continuously:

I can not find any common factor between the instances where this error occurs, so I'm not sure if you can help me with this, but I would very much appreciate it if you could have a look.

Are you able to provide a self-contained example, or test with the current version (0.6) of RichTextFX?

Closing as I cannot reproduce this in the current version.
