arrays with octave-java

[ernst]

Hi all,
i use octave-java 1.2.8 for invoking java code from within octave.
Works well but now i have some strange problem.

arr is an array.
I thought that i could write just arr.length, but does not work.
Then i tried java_get(arr,'length') which did not work either.
What did work is by reflection:
java_invoke('java.lang.reflect.Array', 'getLength', arr);

This seems overkill to me.

How to get a smooth solution?

regards,
ERnst
