Andi Vajda commented on PYLUCENE-41:
------------------------------------
The bug is not with creating the JArray('double')([1.0, 2.0]) array. This works
with both python 2 and 3.
What is not working in jcc on python 3 is setting this array into the other
array you created:
>>> a=JArray('object')(5)
>>> a[0] = JArray('double')([1.0, 2.0])
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: JArray<double>[1.0, 2.0]
Nor does casting it to Object work:
>>> from java.lang import Object
>>> JArray('double')([1.0, 2.0]).cast_(Object)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: <class 'Object'>
This all seems to work fine in python 2, however.

> Hi,
>
> In JCC 3.0 release version and early(2.7) it is possible to make a double
> array by:
>
> {{mask = JArray('object')(5)}}
> {{for i in range(5)}}
> {{ mask[i] = JArray('double')([1.0, 2.0])}}
> It gives in the <=3.0 following type of 'mask'
> JArray<object>[<Object: [D@3967e60c>, <Object: [D@60d8c9b7>, ...
> for svn version it gives a 'TypeError: JArray<double>[1.0, 2.0]' in the
> assignment to mask[i]
>
> Not sure this is a bug or a change of how to do things.
> Best Regards
