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
例
