CWE-586: Explicit Call to Finalize()

MITRE CWE weakness

Kind Weakness
Abstraction Base
Status Draft
Likelihood of exploit

Description

The product makes an explicit call to the finalize() method from outside the finalizer.

While the Java Language Specification allows an object's finalize() method to be called from outside the finalizer, doing so is usually a bad idea. For example, calling finalize() explicitly means that finalize() will be called more than once: the first time will be the explicit call and the last time will be the call that is made after the object is garbage collected.

Common consequences

  • Integrity, Other: Unexpected State, Quality Degradation

Mitigations

Implementation — Do not make explicit calls to finalize().
