This should work nicely (with 0.94; 0.96 does not exist yet ;-))

<fo:block linefeed-treatment="preserve"
           white-space-treatment="preserve"
           white-space-collapse="false">
{A Java class}
</fo:block>

white-space-treatment is equally important to preserve the leading  
spaces of the lines. If this reverts to its initial value of "ignore- 
if-surrounding-linefeed", those will be removed, leading to all lines  
starting at the same offset from the page-edge. I assume it's this  
latter effect Siegfried is referring to as "filled". All indentation  
(most likely inserted as spaces) in the source file will be lost.

Without preserved linefeeds, the linebreaks are calculated as if the  
block's text were prose. For poetry (and incidentally also source  
code ;-)), you need the above properties.

Cheers

Andreas
