First Segment must be moveto

I see Index out of bounds exception using the signature component in two different scenarios based on the log. Is this is a known issue.

Code:

SignatureComponent signC = new SignatureComponent();
  signC.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                Image sourceImage = sign.getSignatureImage().scaledSmallerRatio(300, 100);
                Image mute = Image.createImage(sourceImage.getWidth(), sourceImage.getHeight(), 0xffffffff);
                Graphics g = mute.getGraphics();
                g.setAntiAliased(true);
                g.drawImage(sourceImage, 0, 0);
                act.setSignature(mute);
            }
        });

This seems to be a bug in the SignatureComponent, I added a workaround here: https://github.com/codenameone/CodenameOne/commit/f402d1b27ade9560cd55db1a104f52e004fe1768

This change will be in the update today.
