Concretely, how do I find out which this is?

I tried looking for duplicates in workdir/, but didn't get anywhere.

The error happens at
com.sun.star.report.pentaho.SOReportJobFactory$_SOReportJobFactory.execute(SOReportJobFactory.java:225)
I don't understand where
 workdir/unxlngx6/JavaClassSet/Jar/sun-report-builder/com/sun/star/report/pentaho/SOReportJobFactory$_SOReportJobFactory.class
comes from. I understand that
 workdir/unxlngx6/JavaClassSet/Jar/sun-report-builder/com/sun/star/report/pentaho/SOReportJobFactory.class
is compiled from
 reportbuilder/java/com/sun/star/report/pentaho/SOReportJobFactory.java

You mean in ~/.conf/libreoffice/4? Nah. Deleted that directory.

I have
 SYSTEM_JFREEREPORT=YES
 JFREEREPORT_JAR=/usr/share/java/flow-engine.jar
this file comes from Debian package version 0.9.4-4; I haven't
upgraded this package since I built. So there should be no problem,
right?
