> Key: FOP-3069
> URL: https://issues.apache.org/jira/browse/FOP-3069
> Project: FOP
> Issue Type: Bug
> Components: fo/unqualified
> Affects Versions: 1.1, 2.0, 2.1, 2.2, 2.3, 2.4, 2.6, 2.7
> Reporter: Michael Kainzbauer
> Priority: Major
>
> +_Since Apache FOP 1.1 (not reproducible in 1.0)_+
> When disabling strict-validation, ApacheFOP will loop infinitely when a
> <fo:table.body> is empty, e.g.: <fo:table.body/>
> As a result in class
> {color:#57d9a3}org.apache.fop.layoutmgr.BlockContainerLayoutManager.getNextKnuthElements(LayoutContext
> context, int alignment);{color}
> (line 111)
> is called infinitely.
> Yes, the XML-FO is incorrect and not according to the standard, but this is
> an issue that can cause real trouble when the given conditions are met.
> Turning on strict-validation will result in an error with a clear and
> understandable error message:
