CWE-586 对Finalize()的显式调用

Explicit Call to Finalize()

结构: Simple

Abstraction: Variant

状态: Draft

被利用可能性: unkown

基本描述

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

扩展描述

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.

策略:

Do not make explicit calls to finalize(). Use static analysis tools to spot such instances.

示例代码

The following code fragment calls finalize() explicitly:

bad Java


// time to clean up

widget.finalize();
