The problem here is Decimal's __tojava__ method does not handle the case of __tojava__(Double.class). We could fix that in Decimal but what would be better (in this respect) is having Decimal.__tojava__ fallback to super.__tojava__ when it doesn't know how to handle the conversion.

This would fix the problem because PyObject.__tojava__ will try conversion to Double.class via __float__.

We would have to expose __tojava__ on the object class for that fix though (it currently is not exposed to Python code). I'm not sure that's so good either
