Details:

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.
