Reino: Code Quality

Códigos de baixa qualidade levam a comportamentos imprevisíveis. Da perspectiva do usuário, isso normalmente se manifesta como usabilidade ruim. Para um invasor, trata-se de uma oportunidade para atacar o sistema de formas imprevistas.

Code Correctness: Call to Thread.stop()

Abstract
O programa chama o método stop() de um thread, possivelmente deixando vazar recursos.
Explanation
Na maioria dos casos, uma chamada direta para o método stop() de um objeto Thread é um bug. O programador pretendia parar a execução de um thread, mas não sabia que esta não é uma maneira adequada de fazer isso. A função stop() dentro de Thread causa uma exceção ThreadDeath em qualquer lugar dentro do objeto Thread, provavelmente deixando objetos em um estado inconsistente e possivelmente deixando vazar recursos. Como essa API é inerentemente insegura, seu uso foi preterido há muito tempo.

Exemplo 1: O seguinte trecho de um programa Java chama equivocadamente Thread.stop().


...
public static void main(String[] args){
...
Thread thr = new Thread() {
public void run() {
...
}
};
...
thr.start();
...
thr.stop();
...
}
