Is it possible to provide auto conversion from Python list to Java array?

[Fanoid]

The auto type conversion in py4j for primitive types are very convenient when calling methods.
But, when Java methods has arrays as the parameters, I have to manually create the array using new_array from Python list or some iterables.
It drives me crazy when I need to write codes for many (tens or hundreds) such methods.

I was trying to write a general conversion from Python list to Java array, but found the type matching are very complex without reflection.

So any good ideas to do this conversion automatically?
