Description

An extra blank line is sometimes added in the header in PDF book output. The problem appears and disappears chapter by chapter, sometimes on the even pages, sometimes on the odd pages, sometimes on both. Pascal Sancho responded to my question on fop-users (16 Feb 2011), with the following:

"FOP seems to be wrong here when a marker is used twice.
As a workaround, you can insert an ZWNJ (​ before the
fo:retreive-marker, that should do the trick (see attached FO snippet)."

His work-around results in correct PDF output.

The problem occurs with both FOP 1.0 and FOP trunk.
