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

             Summary: NullPointerException in 
org.apache.commons.imaging.formats.gif.GifImageParser.getMetadata() when 
GraphicControlExtension is null 
                 Key: IMAGING-282
                 URL: https://issues.apache.org/jira/browse/IMAGING-282
             Project: Commons Imaging
          Issue Type: Bug
          Components: Format: GIF
    Affects Versions: 1.0-alpha2
            Reporter: Samuel Monsarrat
         Attachments: problem.gif

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.
