ParsingEncoder#push IndexOutOfBounds

[Daniel Campelo]

Hello,

I'm getting the following exception:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 46

Think this can be solved by changing ParsingEncoder#push() implementation

    if (pos == counts.length) {
      counts = Arrays.copyOf(counts, pos + 10);
    }
    counts[++pos] = 0;

With

    if (++pos >= counts.length) {
      counts = Arrays.copyOf(counts, pos + 10);
    }
    counts[pos] = 0;


Cheers,
