According to
http://de.mathworks.com/help/matlab/matlab_external/passing-data-to-a-java-method.html,
char mxn with m,n>1 shall be converted into String[].
What happens is that it is converted into String.

With the java class attached, try:


t=javaObject('eu.simuline.octave.OctaveInterfaceTester')


and then


t.str=['ab';'cd';'ef'].


This is really nonsense because str has type String.
Nevertheless:
t.str yields 'ab'.

The problem is in ov-java::unbox
where also ['ab';'cd';'ef'] is a string value
converted into an UTF-string.
