Dave Roxburgh commented on FOP-3098:
------------------------------------
The attached patches resolve this issue (patch.txt) and add an appropriate
layout unit test (patch_cached.txt).
The bug was caused by the first fo:block inside the fo:list-item-body ending at
the same page-height as the float. ListItemLayoutManager then set the page
reset position (originalBodyPosition) to a ListItemContentLayoutManager instead
of a BlockLayoutManager (the second block in the list-item-body) which caused
the BlockStackingLayoutManager to fall over when assembling the blocks required
to render the page. The fix looks ahead in the Knuth elements to find the
second block and sets that as reset position.

> Doing a FOP translation with the given XSL and XML input files lead to a
> Nullpointer Exception.
> If the text block is shortened by one character ("dataX" -> "data") then the
> translation succeeds.
> If the text block is replaced by "lore ipsum" of the same length then the
> translation succeeds also.
