Description
When I do an example method call where the return type is double[][], I get the following output
julia> jcall(obj, "getDoubles", Array{Array{jdouble, 1}, 1}, ())
Ptr{Void} @0x0000000008ff5340

Research direction
Start by reproducing the jcall example using the double[][] return type Array{Array{jdouble, 1}, 1}. Trace how JavaCall.jl handles this return type and verify that the result is converted to a Julia nested array rather than displayed as Ptr{Void}.
