Description

JArray objects use the legacy _getslice_ implementation, and hence aren't sliceable in Python 3.

In []: lucene.JArray_byte(b'abc')[:]
...
TypeError: sequence index must be integer, not 'slice'

I'm not necessarily advocating that they should be sliceable, just that it's a regression. It's also worth noting that slices returned Python sequences, not JArray objects, which I think is worth revisiting if it's going to be re-implemented anyway.
