-----------------------------------------

Could you extract the extract the font from the PDF file, also post the complete stack trace? And why is the code you posted not the source code, did you modify something? I'm wondering what's going on.

> While processing todays batch of data we got a Nullpointer exception in getLeftSideBearing. Sadly I can't give you the PDF.
> ```
>     public int getLeftSideBearing(int gid) {
>         return gid < this.numHMetrics?this.leftSideBearing[gid]:this.nonHorizontalLeftSideBearing[gid - this.numHMetrics];
>     }
> ```
> In this function there could be a case where nonHorizontalLeftSideBearing is null and you still ask for a GID in larger or equal to numHMetrics.
> First time I see this issue and so far only 4 characters in one PDF has this issue so not critical.
