Error trying to create PDF with accessibility

Hello I'm working in a quite complex java (1.8.0_112) project, using apache-fop 2.2. Windows 10 OS.


It seems that the <accessibility> tag is ignored in the xconf file so I had to enable it programatically.


After that, I get the following exception when rendering pdf with accessibility enabled:

The above-mentioned line 160 is:

      <fo:page-sequence master-reference="onlySeq" language="fr-FR" country="fr">



Maybe I'm missing something? I may try to create a full example if needed.
