Right !

Wrong Java version it is !!! You were right !
I checked my java installation (aptitude):
openjdk-7-jre / openjdk-7-jdk were not intalled, only openjdk-7-jre-headless or
openjdk-6-jre and openjdk-6-jdk were.
I did the following :
- installed openjdk-7-jre and jdk
- did a update-java-alternatives -s java-1.7.0-openjdk-i386
- checked that java -version output gave version 1.7
- purged and reinstalled octave-java
Not sure if everything was required, but it now works...
Thanks very much for your advice !
Alex
