The code in question is:
} catch (Exception e) {
if (!((_ok) ? true : (Math.random() > 0.1))) {
return res;
}
(error logging)
_ok = false;
}
A 10% percent chance to skip logging under certain circumstances. Very strange code, and a strange way to write it. Also wouldn't this be equivalent to
if (!_ok || (Math.random() > 0.1))
