Serious Issue: JPG Image thumbnail showing as /file_system/large/image.png

[10年前 に Pushpinder Singh によって更新されました。]

Liferay Portal Enterprise Edition 6.1.20 EE (Paton / Build 6120 / July 31, 2012)

Liferay production environment is showing loaded JPG image thumbnails as /file_system/large/image.png rather than correct file.

When we access same images from URL, it is showing fine (because of direct url to image in liferay repository)

Some JPG files (taken from IPhone) are showing correctly as thumbnail.

Same images when loaded in test or development environment are showing fine too.

We loading image using control panel in 'Document and Media' menu.

This seems serious issue to go live.

Will appreciate any advise or hint.

Seems that images aren't detected as real images, so thumbnail isn't created (or there are errors while trying to).

Did you see any error in server logs when uploading those images?

Following exception is showing in log after adding trouble some images through control panel.

Seems you have to add this JVM parameter:

-Djava.awt.headless=true

when starting your Liferay server.

Thanks Juan. Adding suggested options -Djava.awt.headless=true solved the problem.
