jcodec: BufferOverflowException with random pixel colors

JCodec version: most recent commit (790187004ba801a98743a52fb40e02b8a22be712)

Minimal (non)working example:

import java.io.File;
import java.io.IOException;
import java.util.Random;

import org.jcodec.api.SequenceEncoder8Bit;
import org.jcodec.common.model.ColorSpace;
import org.jcodec.common.model.Picture8Bit;


public class CrashTest
{
    public static void main(String[] args) throws IOException
    {
        final SequenceEncoder8Bit seqEncoder = SequenceEncoder8Bit
                .createSequenceEncoder8Bit(new File("out.mp4"), 30);

        final Picture8Bit pic = Picture8Bit.create(1920, 1080, ColorSpace.RGB);

        byte[] picData = pic.getPlaneData(0);
        new Random().nextBytes(picData);

        seqEncoder.encodeNativeFrame(pic);

        seqEncoder.finish();
    }
}

Which results in:
