            <title>[JAVA-3515] Work around Collectors.toMap NPE bug</title>
                <link>https://jira.mongodb.org/browse/JAVA-3515</link>
                <project id="10006" key="JAVA">Java Driver</project>
                    <description>&lt;p&gt;The recent &lt;a href=&quot;https://jira.mongodb.org/browse/JAVA-1788&quot; title=&quot;Insert method should return a result instead of void&quot; class=&quot;issue-link&quot; data-issue-key=&quot;JAVA-1788&quot;&gt;&lt;del&gt;JAVA-1788&lt;/del&gt;&lt;/a&gt; support for returning results from insertions uses &lt;tt&gt;Collectors.toMap&lt;/tt&gt; which contains a &lt;a href=&quot;https://bugs.openjdk.java.net/browse/JDK-8148463&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;bug&lt;/a&gt; in the openJDK when collecting null values.&lt;/p&gt;

&lt;p&gt;The perf tests highlight this bug as any bulk inserts of &lt;tt&gt;RawBsonDocuments&lt;/tt&gt; will trigger it on openJDK 8 &amp;amp; 11.&lt;/p&gt;</description>
