Reports <code>Runnable</code> passed to a <code>Cleaner.register()</code> capturing reference being registered.
|
|
If the reference is captured, it will never be phantom reachable and the cleaning action will never be invoked.
|
|
<p>Possible sources of this problem:</p>
|
|
<ul>
|
|
<li>Lambda using non-static methods, fields, or <code>this</code> itself</li>
|
|
<li>Non-static inner class (anonymous or not) always captures this reference in java up to 18 version</li>
|
|
<li>Instance method reference</li>
|
|
<li>Access to outer class non-static members from non-static inner class</li>
|
|
</ul>
|

|
<p>Sample of code that will be reported: </p>
|
|
<pre><code>
|
|
int fileDescriptor;
|
|
Cleaner.Cleanable cleanable = Cleaner.create().register(this, () -> {
|
|
System.out.println("adsad");
|
|
//<i>this</i> is captured via <i>fileDescriptor</i>
|
|
fileDescriptor = 0;
|
|
});
|
|
</code></pre>
