yeah, I'm aware that the null initialization is redundant in java;
that's probably just a C++ habit leaking through. I'll remove that.

the assignment however cannot coincide with the declaration, because
this is one of those "efficiency oriented" java APIs (pass in null if
you want the callee to allocate the array), and writing a literal
"null" in position of the "samples" argument degrades the type of the
argument to Object, which ambiguates the call: there's an overload for
each of int[], double[] and float[].
