I'm trying to call a native method that has an array of structs as a method argument. I keep getting an IllegalArgumentException: Structure array elements must use contiguous memory (at element index 1)

I've made some example code to illustrate/reproduce my problem. I'm using the latest JNA code from svn (revision 453).

interface Test extends Library {

class MyNumber extends Structure { public short num; }

int calculateSum(MyNumber[] numbers); }

When I link to the DLL and I call calculateSum from a Junit test I get the exception. My C++ code looks like this (although I think the problem doesn't lie there):

typedef struct MyNumber { unsigned short num; } MyNumber;

TEST_API int calculateSum(MyNumber* numbers) { int size = sizeof(numbers) / sizeof(MyNumber); int result = 0;

for (int i = 0; i < size; i++) { result += numbers[i].num; }

return result; }

Did I stumble upon a bug or am I doing something wrong? Any help will be greatly appreciated!

Thanks, Niels.
