I changed the control file in the debian package (see attachments).

default-jre-headless is now not in "Depends" but in "Build-Depends" and
"Recommends". The resulting octave-debian packages does the job.

In case somebody wants to use the java-interface, the above error
message seems good enough.

Please consider repackaging Octave with the modified control file.

Description: GNU Octave language for numerical computations
 Octave is a (mostly Matlab (R) compatible) high-level language, primarily
 intended for numerical computations. It provides a convenient command-line
 interface for solving linear and nonlinear problems numerically.
 .
 Octave can be dynamically extended with user-supplied C++ files.
