Hi, After some further tests, this NPE is caused by a fo:footnote within a fo:block-container in absolute position and/or with a specified height.
1/ You should fill in a bug for that. 2/ why do you need a footnote in a fo:block-container in absolute position? Since you control the posistion of its content, I think you shoud use the same thing for the note, and put it in a fo:block-container in absolute position... WDYT?
