I am the maintainer of the octave-java package . It is now included in octave since version 3.8 and has been deprecated by the developers. Please remove.
[#octave] 20:10 < drizzd> With Octave 3.8 the java package now shadows a lot of core library functions. Are the functions now built-in and the package is deprecated? 20:12 < carandraug> drizzd, yes 20:13 < drizzd> carandraug: thanks 20:13 < carandraug> drizzd, the java package was included in 3.8. It was not a separate work. But we keep it in OF for users with older versions
