it still might be worth a follow-up bug. As it is, calling `System.gc()` each time through the loop means that you are creating far fewer objects than you would in a tight loop (by an order of magnitude based on a few quick tests I did).

> For the OOME - there seems to be no leak, since the memory usage drops down to initial values either using `System.gc()` in the loop, or when running in the IDE with the large heap: the memory fills up rather quickly, then drops again down to low value when one hits "Run GC" in the VirtualVM for example.

When I run it with `-verbose:gc` I see the memory continually increasing, although slowly. I'll try it with Visual VM and see if I spot anything. In any case, if there is a leak here, it isn't a large one (and isn't directly related to this bug), so would be something to look into as a follow-up.
