oXygen stalls creating PDF file

This one has got me a couple of times recently, so it's probably more for my benefit than anyone else's.

When generating PDFs using oXygen, the PDFs are created correctly when using oXygen's internal DITA-OT. However, when I switch to using my own DITA-OT, the transform stalls when creating the .PDF from the .FO. As usual, oXygen's tech support came to the rescue...

Seems that "with Windows XP, Apache FOP blocks the console before the PDF is generated", whatever that means.

oXygen have introduced a patch into their internal DITA-OT to get around this. So you need to copy this patch across to your external DITA-OT version to benefit from the patch:

1. In the build.xml file, search for the "transform.fo2pdf.fop" target.
2. Comment out the target template and replace it with the following one:

<target name="transform.fo2pdf.fop" if="use.fop.pdf.formatter">
<java classname="org.apache.fop.cli.Main" fork="yes" classpath="${java.class.path}" dir="${dita.map.output.dir}" failonerror="true">
  <arg line="-fo "${inputfile}" -pdf "${outputFile}" -c "${fop.home}/conf/fop.xconf"/>
<java>
<target>
