PDFBOX-3327: simplify and avoid alleged IOOBE as proposed by Tim Koopman
> IndexOutOfBoundsException when retrieving kerning information
> -------------------------------------------------------------

> Key: PDFBOX-3327

> Issue Type: Bug
> Components: FontBox

> Reporter: Tim Koopman

> Priority: Minor

>
>
> When using TrueTypeFont::getKerning there is a large possibility that you
> will run into an out of bounds exception. This is because the binary search
> is split into two parts, and the second part incorrectly adds the offset to
> the found index.
> Actually, with the current implementation there is no need to split the
> search into two parts. This is only 'needed' when using a binary search
> implementation which is optimised for cases where the length of the array is
> a power of two, which Arrays::binarySearch doesn't implement.
