You need this patch (incorporated in the octave-java package):

 http://anonscm.debian.org/gitweb/?p=pkg-octave/octave-java.git;a=blob;f=debian/patches/libjvm.patch;h=cc847293d00ae09ac74e8eca833dbafdd48918a2;hb=19a7fdc2264cb0166f5324677bf2615252fda8e3

Also, /usr/lib/jvm/default-java points to OpenJDK 6 on my Debian sid
system. If you want to select OpenJDK 7, you need to set the JAVA_HOME
variable to:

 export JAVA_HOME = /usr/lib/jvm/java-7-openjdk-amd64

(this is done in debian/rules of the octave-java package).
