AppleScript do script file completely broken in Acrobat 9 Pro?

Question

After not being able to use Acrobat 8 at all because of this issue
http://www.adobeforums.com/webx/.59b4b95a
I plunked down another $170 hoping the issue would be fixed in Acrobat 9.
But with Acrobat 9 Pro (9.0.0, OS X 10.5.5), calling do script file does not seem to work at all. I've created a simple one line script:
console.println("test 123");
and called it like this:
tell application "Adobe Acrobat Pro"
do script file "Path:to:file:test.js" as alias
end tell
I get this error:
92:181: execution error: Adobe Acrobat Pro got an error: Can't continue do script. (-1708)
The console in Acrobat Pro shows:
illegal character
0:
Thanks for any help or suggestions.

Answer 1

It depends. Generally-speaking the content of PDF files created in Acrobat X will use PDF/1.7 as the base level so will open in Acrobat and Reader 9, but there are exceptions, including:
PDF Portfolios won't display properly
PDFs using the 'Acrobat X or later' security hash won't open at all
Some edge case scenarios with certification won't validate
Files which exploit bugs in one version or which hit a bug in a previous version
All PDFs created in Acrobat (Standard or Pro) will  open in the same version of Reader, Standard or Pro - it's only the creation/editing features which vary between flavors.
