Thanks for the prompt reply.

In fact, it works OK with the jython command with version 2.5.2 as well:

$ jython
Jython 2.5.2 (Release_2_5_2:7206, Mar 2 2011, 23:12:06) 
[Java HotSpot(TM) 64-Bit Server VM (Oracle Corporation)] on java1.8.0_60
Type "help", "copyright", "credits" or "license" for more information.
>>> from attributeTest import DoubleHolder
>>> d = DoubleHolder()
>>> print d.number
0.0
>>> d.number = 3.0
>>> print d.number
3.0

However, we use Jython in an interactive GUI built in Java. The PythonInterpreter that we instantiate there is giving this error.

As the order of the methods is not guaranteed, it might sometimes work but do not work other times. The map mentioned in the analysis section should be sorted as explained there.
