CWE-572 调用线程的run()方法而非start()方法

Call to Thread run() instead of start()

结构: Simple

Abstraction: Variant

状态: Draft

被利用可能性: unkown

基本描述

The program calls a thread's run() method instead of calling start(), which causes the code to run in the thread of the caller instead of the callee.

扩展描述

In most cases a direct call to a Thread object's run() method is a bug. The programmer intended to begin a new thread of control, but accidentally called run() instead of start(), so the run() method will execute in the caller's thread of control.
