|

|

<p>The PMD team is pleased to announce PMD 6.18.0.</p>
|
||
|
||
<p>This is a minor release.</p>

<h3 id="new-and-noteworthy">New and noteworthy</h3>

<h4 id="new-rule-designer-documentation">New rule designer documentation</h4>
|
||
|
||
<p>The documentation for the rule designer is now available on the main PMD documentation page:
|
||
<a href="pmd_userdocs_extending_designer_reference.html">Rule Designer Reference</a>. Check it out to learn
|
||
about the usage and features of the rule designer.</p>
|
||
|
||
<h4 id="new-rules">New rules</h4>
|
||
|
||
<ul>
|
||
<li>The Java rule <a href="pmd_rules_java_bestpractices.html#avoidmessagedigestfield"><code class="highlighter-rouge">AvoidMessageDigestField</code></a> (<code class="highlighter-rouge">java-bestpractices</code>) detects fields
|
||
of the type <code class="highlighter-rouge">java.security.MessageDigest</code>. Using a message digest instance as a field would need to be
|
||
synchronized, as it can easily be used by multiple threads. Without synchronization the calculated hash could
|
||
be entirely wrong. Instead of declaring this as a field and synchronize access to use it from multiple threads,
|
||
a new instance should be created when needed. This rule is also active when using java’s quickstart ruleset.</li>
|
||
</ul>
|
||
|
||
<h4 id="modified-rules">Modified Rules</h4>
|
||
|
||
<ul>
|
||
<li>The Java rule <a href="pmd_rules_java_errorprone.html#closeresource"><code class="highlighter-rouge">CloseResource</code></a> (<code class="highlighter-rouge">java-errorprone</code>) now ignores by default instances
|
||
of <code class="highlighter-rouge">java.util.stream.Stream</code>. These streams are <code class="highlighter-rouge">AutoCloseable</code>, but most streams are backed by collections,
|
||
arrays, or generating functions, which require no special resource management. However, there are some exceptions:
|
||
The stream returned by <code class="highlighter-rouge">Files::lines(Path)</code> is backed by a actual file and needs to be closed. These instances
|
||
won’t be found by default by the rule anymore.</li>
