This is strange. I can't think of a reason for this difference in execution. My impression is that the exceptions worked some weeks or a few months ago. And what has changed since is the Ubuntu OS updates. I tried both these Java JDK: $ java -version openjdk version "1.8.0_111" OpenJDK Runtime Environment (build 1.8.0_111-8u111-b14-2ubuntu0.16.10.2-b14) OpenJDK 64-Bit Server VM (build 25.111-b14, mixed mode) java -version java version "1.8.0_121" Java(TM) SE Runtime Environment (build 1.8.0_121-b13) Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode) My OS is uname -a Linux jmv-SMBIOSation 4.8.0-34-generic #36-Ubuntu SMP Wed Dec 21 17:24:18 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux Instead of working in a Scala eclipse environment, I downloaded a fresh Jena 3.1.1, and tried again: SAME THING ! cd ~/apps/apache-jena-3.1.1 for f in lib/*; do JENA=$JENA:$f; done javac -cp $JENA ReadMgr.java java -cp $JENA ReadMgr log4j:WARN No appenders could be found for logger (Jena). log4j:WARN Please initialize the log4j system properly. log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info. *size 0* You can force the use of, say RDF/XML, by opening the connection directly > with HttpOp.
