Jfor 0.52 : external graphics

I am looking for the solution of a strange problem with embedding
graphical
files (fo:external-graphic).

When conversion is invoked by executing shell script, all the processing
going OK,
rtf file is created.

Command line would be like the following:
/opt/jdk1.3.1/bin/java -classpath
<fullpath>/jfor/lib/xerces-1.2.3.jar:<fullpath>/jfor/lib/jfor.jar
ch.codeconsult.jfor.main.CmdLineConverter /tmp/rep784465287.fo
/tmp/rep784465287.rtf

However, if the same command is invoked from our application's cgi
script, in this particular case via
Perl's system call, the processing stumbles at exactly this line of
encodeJPEG (byte [] data) method of org.jfor.jfor.tools.jpeg.Encoder:

     Image image = Toolkit.getDefaultToolkit ().createImage (data);

Below is the error output content, where I included a lot my own
debugging stuff, plus
list of the System properties.

Note, I checked the size of data input to
 Image image = Toolkit.getDefaultToolkit ().createImage (data);  
And this size is exactly right. Well, despite it read using 
InputStream.availiable() method ( see bug highlighted in Message:
8686084 ).

Just to compare the environment, here the error log when the command is
executed manually
(not via CGI script), and  where the images are embedded successfully:
