The product contains a finalize() method that does not call super.finalize().
The Java Language Specification states that it is a good practice for a finalize() method to call super.finalize().

Practical mitigations for CWE-568, grouped by where in the lifecycle they apply.
Call the super.finalize() method.
Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)
Effectiveness: High
