UPDATE: I resolved the problem this afternoon. The solution is to install the JAI ImageIO library in the JDK itself. In my case I do not have permissions to update the system's JDK so I installed my own JDK and then installed the ImageIO library there. I rebuilt DSpace using my own JDK and verified that media filtering can now produce thumbnail images for a PDF file.
