It is implemented by interrupt execute thread, it will trigger InterruptedException.so if JobHandler catch this execuption and handle this exception this function is unavailable.
So if you want stop the running task ,the JobHandler need to handle InterruptedException separately by throw this exception.the right logic is as shown below:
```
try{
// TODO
} catch (Exception e) {
if (e instanceof InterruptedException) {
throw e;
}
logger.warn("{}", e);
}
```
If JobHandler start child thread,child thread also must not catch InterruptedException,and it should throw exception.
