I would expect TextLayout.getCarentInfo(TextHit(0,true)[0] to return the first xAdvance instead it is returning the Advance.

TextLayout layout = new TextLayout("Test", getFont());
TextHitInfo thi = new TextHitInfo(0, true);
float[] caretInfo = layout.getCaretInfo(thi);
System.out.println("position: " + caretInfo[0]);
