Description

This finalize() method does not call super.finalize().

The Java Language Specification states that it is a good practice for a finalize() method to call super.finalize().[1]
The statement above is not completely correct. The Java Language Specification 3.0 section 12.6.1 states: "This should always be done, unless it is the programmer's intent to nullify the actions of the finalizer in the superclass."

Risk Factors

TBD

Examples

The following method omits the call to super.finalize().

 protected void finalize() {
                discardNative();
 }
