``++getClass++`` should not be used for synchronization in non-``++final++`` classes because child classes will synchronize on a different object than the parent or each other, allowing multiple threads into the code block at once, despite the ``++synchronized++`` keyword.
Instead, hard code the name of the class on which to synchronize or make the class ``++final++``.
== Noncompliant Code Example
----
public class MyClass {
public void doSomethingSynchronized(){
synchronized (this.getClass()) { // Noncompliant
// ...
}
}
----
== Compliant Solution
----
public class MyClass {
public void doSomethingSynchronized(){
synchronized (MyClass.class) {
// ...
}
}
