Nullpointer exception in InlineStackingLayoutManager

[Rainer Garus <ra...@arcor.de>]

Since several weeks there is a nullpointer exception in InlineStackingLayoutManager.
The appended fo file is the shortest example I can construct to reproduce the error
(using Java 1.3.1_04 on Linux and snapshot xml-fop_20030308173134.tar.gz).

Remarks:

Removing text-align"justify" there is no exception
Removing hyphenate="true" language="de" there is no exception
Removing <fo:inline> and </fo:inline> there is no exception

There is also no exception in the following case:
<fo:inline>
Beantwoord deze vraag met ja, als u met de Cancel bewerking wilt doorgaan, waarop de functie anders
</fo:inline>
