Originally reported at: http://answers.nuxeo.com/questions/6046/cant-generate-picture-thumbnails
In certain (unknown) circumstances, Nuxeo servers can start to fail generating thumbnails, because of the following error:

Once the error starts occurring, it happens every time a picture is uploaded, and even restarting Nuxeo doesn't help. The only time I saw the error disappear for a while is when upgrading a server from 5.7.1 to 5.7.2.
I figured out that the bug is linked to the use of an InputStreamBlob, created to store temporarily the original picture ; the blob is somehow broken when time comes to save the document (maybe the stream is read before?).
I hacked the bug by overriding the PictureViewListener + PictureViewsGenerationWork, replacing the blob right after the thumbnails generation:
...
picture.fillPictureViews(blob, filename, title, pictureTemplates);
// Fix original picture
String originalContentXpath = picture.getViewXPath("Original") + "content";
Serializable originalContent = workingDocument.getPropertyValue(originalContentXpath);
if (originalContent instanceof InputStreamBlob) {
InputStreamBlob originalContentBlob = (InputStreamBlob) originalContent;
Blob persistedBlob = originalContentBlob.persist();
workingDocument.setPropertyValue(originalContentXpath, (Serializable) persistedBlob);
}
For full disclosure, I only experienced these bugs with a customized Nuxeo, with changes made to DAM for instance. But I don't think we did anything that could impact the thumbs generation.
