java抛出MyException并返回NULL

Question

我还有下一个问题

public Validator {

    ....

    public boolean validate() throws MyException
    ....
        if (!model.hasSomeCondition()) {
            throw getException(model);
        }
    ....
    return true;
}

....

public MyException getException (MyModel aModel) {
    MyException exception = new MyException(aModel.getFirstName());
    return exception;
}

....

public static class MyException extends Exception {
 ...
}

....


}

当我捕获异常时，对象始终为空

怎么了？我不明白

另外，谢谢你的帮助
