                            <comment id="1145081" author="jeff.yemin" created="Fri, 15 Jan 2016 15:18:15 +0000"  >&lt;p&gt;Is there any particular reason you opened this in the Java driver project?&lt;/p&gt;

&lt;p&gt;I&apos;d suggest instead that you start a thread on the &lt;a href=&quot;https://groups.google.com/forum/#!forum/mongodb-user&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;MongoDB user forum&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Regards,&lt;br/&gt;
Jeff&lt;/p&gt;
