[jython] Problem with an huge dictionary

[keobox]

Hi,
I apologize if this is not the right group for posting question
related to jython.
Please give me the right directions if this is the case.

The question is:
Is there a limit on the number of entries a dictionary can have i
jython?

I wrote a little app where my data is stored in a huge dictionary
(11746 entries) generated with a python script.
When I try to import the dictionary, jython complains with the
following message:

What can I do to avoid this?
