The code in question is:<p><pre><code>            } catch (Exception e) {
                if (!((_ok) ? true : (Math.random() &gt; 0.1))) {
                    return res;
                }
                (error logging)
                _ok = false;
            }
</code></pre>
A 10% percent chance to skip logging under certain circumstances. Very strange code, and a strange way to write it.  Also wouldn&#x27;t this be equivalent to<p><pre><code>    if (!_ok || (Math.random() &gt; 0.1))</code></pre>
