This PDF file is version 1.3 so it needs at least Acrobat 4.0 PDF preferences window You can see the version number in Acrobat by opening the preferences window and looking at PDF version. With Acrobat it is always one number than the release (so Acrobat 9 supports all versions up to 1.8 while Acrobat 8 only covers up to 1.7).
In order to be confident of displaying the PDF file correctly, you obviously need a program which supports that version. Sun’s Java PDF Renderer does not support many of the features in versions 1.6 and above which is why it fails on lots of PDF files. For example, version 1.6 added a new way to squash down data and reduce the size of PDF files. The current latest version is 1.8 and while it may work in libraries which do not support 1.8, there is no guarantee. There have been several revisions of the PDF file specification, each backward compatible but adding new features. He has an MA in Medieval History and a passion for reading.
