[jira] [Updated] (SANSELAN-53) Bug in Sanselan.getImageInfo(File)
with certain JPEGs causing java.lang.OutOfMemoryError or
java.lang.NegativeArraySizeException
[ https://issues.apache.org/jira/browse/SANSELAN-53?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dominic Early updated SANSELAN-53:
----------------------------------
Attachment: SanselanTest.java
Test driver demonstrates how the two sample files are parsed by javax.imageio without issue, but cause NegativeArraySizeException or OutOfMemoryError when parsed by Apache Sanselan
> Bug in Sanselan.getImageInfo(File) with certain JPEGs causing java.lang.OutOfMemoryError or java.lang.NegativeArraySizeException
> --------------------------------------------------------------------------------------------------------------------------------
>
> Key: SANSELAN-53
> URL: https://issues.apache.org/jira/browse/SANSELAN-53
> Project: Commons Sanselan
> Issue Type: Bug
> Affects Versions: 0.94-incubator
> Environment: Windows, Unix
> Sun Java JVM (multiple versions)
> Reporter: Dominic Early
> Attachments: SanselanTest.java
>
>
> In order to extract JPEG image dimensions, Apache Commons Sanselan (0.97) was used as follows:
> File imgfile = new File("./test.jpg");
> org.apache.sanselan.Sanselan.getImageInfo(imgfile);
> For most JPEG images, this code works as expected. However with specific JPEG files, the call to getImageInfo() causes a repeatable java.lang.OutOfMemoryError or java.lang.NegativeArraySizeException - depending upon the input JPEG file. The same files can be processed with javax.imageio.ImageReader without such issues.
> The OutOfMemoryError is especially serious as it may cause JVM to fail.
