But when I use Java, it return this message

Traceback (most recent call last):

  File "/usr/lib/python3.5/xmlrpc/client.py", line 509, in __dump

    f = self.dispatch[type(value)]

KeyError: <class 'odoo.tools.misc.frozendict'>

During handling of the above exception, another exception occurred:

    raise TypeError("cannot marshal %s objects" % type(value))

TypeError: cannot marshal <class 'odoo.tools.misc.frozendict'> objects

I think it is not my fail.

Please help me.
