> A bug in the usage of the result of a binary search causes a crash in the
> calculation of kerning information. Here's the patch:
> {code}
> --- a/fontbox/src/main/java/org/apache/fontbox/ttf/KerningSubtable.java
> +++ b/fontbox/src/main/java/org/apache/fontbox/ttf/KerningSubtable.java
> @@ -292,7 +292,7 @@ public class KerningSubtable
> index = Arrays.binarySearch(pairs, searchRange, pairs.length,
> key, this);
> if (index >= 0)
> {
> - return pairs[searchRange + index][2];
> + return pairs[index][2];
> }
> return 0;

> {code}
> Explanation: The searchRange parameter is passed to binarySearch(), but the
> result of binarySearch() is relative to the start of the array, not the
> passed-in start. So no need to add searchRange to the result. Adding causes
> the indexing to go off the end of the array.
