 <code class="language-plaintext highlighter-rouge">reportUnusedVariables</code>. Variables whose name starts with <code class="language-plaintext highlighter-rouge">ignored</code> are filtered out, as
 is standard practice for exceptions.</p>
 
+<p>Limitations:</p>
+<ul>
+  <li>The rule currently cannot know which method calls throw exceptions, or which exceptions they throw.
+In the body of a try block, every method or constructor call is assumed to throw.  This may cause false-negatives.
+The only other language construct that is assumed to throw is the <code class="language-plaintext highlighter-rouge">throw</code> statement, in particular,
+things like <code class="language-plaintext highlighter-rouge">assert</code> statements, or NullPointerExceptions on dereference are ignored.</li>
+  <li>The rule cannot resolve assignments across constructors, when they’re called with the special
+<code class="language-plaintext highlighter-rouge">this(...)</code> syntax. This may cause false-negatives.</li>
+</ul>

+<p>Both of those limitations may be partly relaxed in PMD 7.</p>
