> Nullpointer exception in getLeftSideBearing
> -------------------------------------------
>
> Key: PDFBOX-3806
> URL: https://issues.apache.org/jira/browse/PDFBOX-3806
> Project: PDFBox
> Issue Type: Bug
> Reporter: Daniel Persson
> Priority: Minor
>
> 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.
