Apparently this is something that was unexpected by fop:
https://issues.apache.org/bugzilla/show_bug.cgi?id=53817#c3
...
The NPE is thrown when foot-note is declared within the static-before region.
If I move the foot-note to the body, the NPE disappears.
Note that FOP behaves in the same way whatever the version is (tried
against v0.95, v1.0, latest trunk).
That said, IMHO I don't think that a static region is the right place
for a footnote declaration, so author should avoid to use that at this
place, as a good practice/workaround.
