Class SuperFinalizeCheck

  • All Implemented Interfaces:
    Configurable, Contextualizable
    public class SuperFinalizeCheck
extends AbstractSuperCheck

    Checks that an overriding finalize() method invokes super.finalize(). Does not check native methods, as they have no possible java defined implementation.

    References: How to Handle Java Finalization's Memory-Retention Issues; 10 points on finalize method in Java.

    To configure the check: 

     <module name="SuperFinalize"/>

    Example:

     public class A {
      protected void finalize() throws Throwable {
         System.out.println("In finalize block");
          super.finalize(); // OK, calls super.finalize()
      }
 }
 public class B {
      protected void finalize() throws Throwable { // violation
          System.out.println("In finalize block");
      }
 }
