Java X11 Dependencies
On Unix-based operating systems, the Java runtime makes use of certain parts of the platform's native X11 graphics libraries. The X Server does not have to be running, but the libraries must be available on the server. Confluence will run on a server that does not have Xlib installed, but parts of the application that manipulate graphics: PDF exports, image thumbnailing, the image gallery macro, CAPTCHA, and the resizing of profile pictures, will fail.
 | Mac OS X
You do not need to install X11 on Mac OS X, as it has its own graphics libraries. |
If X11 is not present, you may see any of the following errors
- "This Confluence installation can not generate thumbnails: no image support in Java runtime"
- "Exception in thread "main" java.lang.UnsatisfiedLinkError: /usr/local/j2sdk1.4.2_09/jre/lib/i386/libawt.so: libXp.so.6: cannot open shared object file: No such file or directory" when exporting a PDF
- "NoClassDefFoundError" when uploading a profile picture
