> I'm using the "last stable version" of Apache Sanselan 0.97 in an Android project (app). I have not upgraded to Commons Imaging yet, since the website says there is no stable release yet. Meanwhile, there are bugs in Sanselan.
> If I run the [sample code method WriteExifMetadataExample.changeExifMetadata|http://svn.apache.org/repos/asf/commons/proper/sanselan/trunk/src/test/java/org/apache/sanselan/sampleUsage/WriteExifMetadataExample.java?p=820841] on an image, which updates the Apterture and GPS tags, the resulting image fails to validate (through Phil Harvey's [ExifTool software|https://sno.phy.queensu.ca/~phil/exiftool/]):

> I need some advice on how to proceed here. Since Sanselan does not appear to do what it should (even on very basic metadata editing), am I correct to assume that the current version of Commons Imaging does a better job? :-)
