>                 Key: FOP-2176
>                 URL: https://issues.apache.org/jira/browse/FOP-2176
>             Project: Fop
>          Issue Type: Bug
>          Components: page-master/layout
>    Affects Versions: 1.0, 1.1
>            Reporter: Alexis Giotis
>             Fix For: trunk
>
>         Attachments: input.fo.xml, output-actual.pdf, output-expected.pdf
>
>
> Render the input.fo.xml using
> ./fop input.fo.xml -pdf output-actual.pdf
> One would expect that the number of lines placed in the left and right column would be equal. But, the right column contains one more line. If, the input.fo.xml, the margin-top="206.m" is changed to margin-top="206.1mm", then we get the expected output (output-expected.pdf)
> This was found while testing the new column balancing algorithm (FOP-1840), but as commented [1], the problem exists elsewhere in the layout engine.
