Yes, the demosite runs on Linux.

This class is part of JAI:
http://java.sun.com/products/java-media/jai/forDevelopers/jai-apidocs/com/sun/media/jai/codec/FileCacheSeekableStream.html

so to me this very much looks like a problem related to the
(improper!?) installation of JAI.

This class comes with jai_codec.jar:
$ jar tf /usr/local/share/java/jre/lib/ext/jai_codec.jar | grep eCacheSeek
com/sun/media/jai/codec/FileCacheSeekableStream.class

Do you have that file inside your java installation?

Did you install the bundles of the form *-jdk* for installation into a
JDK (or bundles of the form *-jre* for installation into a JRE,
whatever are you using?).
Just a guess.
