Hi
Attached is the FO file (

book.xml_fo_with_problem.xml ) and a PDF showing the two offending
lines
that used to wrap correctly with the old FOP and DB stylesheets (
http://www.nabble.com/file/p19222600/fop_testing_wrap_test.pdf
fop_testing_wrap_test.pdf ).
The first line is on Adobe page 19, and the second is on Adobe page
34.
AFAIU, this is a known 'issue'. (see also: https://issues.apache.org/
bugzilla/show_bug.cgi?id=43474)
Issue-between-quotes because, in spite of the default value for wrap-
option being "wrap", strictly speaking, this only indicates that the
formatter MAY (not MUST) insert implicit line-breaks. The method by
which those are determined is left up to the implementation. FOP uses
Unicode TR#14 (see: http://unicode.org/reports/tr14/) as a reference,
and there, a break between two arbitrary alphanumeric characters is
not considered, unless the two are separated by a space (which can
also be a zero-width space).
As long as no one finds the time/energy to implement real line-
wrapping on top of that, the workaround is to customize the
stylesheet to insert zero-width spaces at strategic positions in the
uninterrupted strings that would not fit on a single line. FOP will
then gladly use these as additional break-possibilities.
HTH!
Cheers
