Q: I got this Exception on Solaris during setup, how to fix it? 
   java.lang.InternalError: Unsupported 16-bit depth

A: On unix/linux systems, sometimes there are multiple Java versions installed, and
   if you are running the wrong Java, all kinds of Exception may occur. So, you may
   want first check the version with 'java -version'.

   This Exception may however be real if you are running the X session in 16-bit color.
   JRE only supports 8-bit or 24-bit (or 32-bit). You need set the color accordingly.
