>    Affects Versions: 1.0-alpha2

> The attached gif file produces a NullPointerException in org.apache.commons.imaging.formats.gif.GifImageParser.getMetadata() l553 due to variable id not having a GraphicControlExtension component (id.gce = null).
> This is set to null in findAllImageData l715.
> Elsewhere in org.apache.commons.imaging.formats.gif.GifImageParser is tested for null (l746).
> This gif seems to contain incorrect metadata. Simply re-saving it with ImageMagick correct the issue but since the gif is correctly displayed by all viewers at my disposal it would seem that org.apache.commons.imaging needs to be more permissive.
