PDF files can not be (reliable) viewed in Confluence 5.x.x
CONF-31759 workaround doesn't change this... deals with other topic)
Let me sum up what I've learned about the bug:
- occurs predominant on Windows hosted system
- 1st view of pdf always works
- after time Confluence starts creating *.part files in viewfile directory (in additon to the existing -> from now on some pages of the pdf are not rendered (the bug)
- the viewfile directory and it's temp directory is heavily used under Windows during viewing a pdf if you delete the content of the viewfile directory and it's temp, 1st view of pdf always works (so a startover)
And this cannot be debugged to it's root cause and fixed by Atlassian ?
