Hi everybody,
I recently migrated our XWiki Windows Server installation to an Ubuntu
Server 14.10 (x64) setup with XWiki 7, Tomcat 8, Java 8 and Nginx proxy.
All issues that occurred were fixed and everything is running smoothly now
except for one thing.
JPG images don't show up on XWiki, I get the error output appended below.
The crucial line seems to be: "Could not initialize class
com.sun.imageio.plugins.jpeg.JPEGImageReader". I searched on google and
downgraded to JRE 7 but that didn't fix the issue so I re-installed JRE-8
and purged JRE-7 again.
Could someone please point me in the right direction how to fix this?
