Google Gson - deserialize list object? (generic type)
... hassle with the Type object, and if you really need a list you can always convert the array to a list by:

Rounding up to next power of 2
... for a 32-bit value:
Round up to the next highest power of 2
unsigned int v; // compute the next highest power of 2 of 32-bit v
v--;
v |= v >> 1;
v |= v >> 2;
v |= v >> 4;
v |= v >> 8;
v |= v >> 16;
v++;
The extension to other widths should be obvious.
