            <title>[JAVA-832] NumberLong is not properly round tripped by the JSON serializer / deserializer</title>
                <link>https://jira.mongodb.org/browse/JAVA-832</link>
                <project id="10006" key="JAVA">Java Driver</project>
                    <description>&lt;p&gt;the JSON serializer (used in most outputs) writes Number / NumberInt / NumberLong as just a regular number.&lt;br/&gt;
The JSON deserializer tries to be smart and either uses a Number or a NumberInt based on how large it is.&lt;br/&gt;
The behavior should be equivalent to the shell or mongoexport / import.&lt;br/&gt;
At the minimum it should encode NumberLong as &lt;/p&gt;
{ $long: N }
&lt;p&gt; so that it can be round tripped.&lt;/p&gt;</description>

If this was needed in other tools, would make sense to have it in the extended spec and drivers.&lt;/p&gt;</comment>

                            <comment id="340202" author="antoine" created="Tue, 21 May 2013 00:10:59 +0000"  >&lt;p&gt;Overall the driver does not abide by the rules here:&lt;br/&gt;
&lt;a href=&quot;http://docs.mongodb.org/manual/reference/mongodb-extended-json/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://docs.mongodb.org/manual/reference/mongodb-extended-json/&lt;/a&gt;&lt;br/&gt;
The Java driver&apos;s output was implemented at a time when both the shell and mongoexport where doing things without real logic (e.g. a date would be just a string).&lt;br/&gt;
The rules were defined later on...&lt;/p&gt;

&lt;p&gt;Anyway I just looked at JSON.parse() code and it detects double vs int vs long, so at least data will not be lost there.&lt;br/&gt;
But it could switch long values to int if they are not large enough, I wonder if that could cause problems, that&apos;s why there is NumberLong in shell.&lt;/p&gt;</comment>
