            <title>[JAVA-3240] No exception thrown when attempting sharded transactions on 4.2	</title>
                <link>https://jira.mongodb.org/browse/JAVA-3240</link>
                <project id="10006" key="JAVA">Java Driver</project>
                    <description>&lt;p&gt;The 4.0 transaction spec says:&lt;/p&gt;

&lt;blockquote&gt;&lt;p&gt;startTransaction SHOULD report an error if the driver can detect that transactions are not supported by the deployment. A deployment does not support transactions when the deployment does not support sessions, or maxWireVersion &amp;lt; 7, or the topology type is Sharded&lt;/p&gt;&lt;/blockquote&gt;

&lt;p&gt;&lt;a href=&quot;https://github.com/mongodb/specifications/blob/cf7248b2574b1a5397a6e18362acfe66f2b55a43/source/transactions/transactions.rst#starttransaction&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/specifications/blob/cf7248b2574b1a5397a6e18362acfe66f2b55a43/source/transactions/transactions.rst#starttransaction&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;However, the Java driver never implemented this check. When 3.10.1 runs a transaction against MongoDB 4.2, it will get an error like this on the first command that goes to a new mongos:&lt;/p&gt;

&lt;p&gt;Message: Throw MongoClientException for sharded cluster transactions&lt;/p&gt;

&lt;p&gt;This version of the driver does not support sharded cluster&lt;br/&gt;
transactions, so should throw a MongoClientException it an application&lt;br/&gt;
attempts it.&lt;/p&gt;
