    _______________________________________________________

Details:

The length of a java array shall be returned using the length attribute: 

a=javaArray('java.lang.Object',1,2);a=a(1)

yields (this is a little more complex because of another bug): 

a =
<Java object: java.lang.Object[]>

Then we would expect a.length
to return 

ans = 
2 

but obtain 
error: [java] java.lang.NoSuchFieldException: length

As a field is expected as for non-array objects. 

Suggestion for a bugfix is to add also method is_java_array.
