java - return 语句 - finally block 未正常完成

Question

已提出类似问题here 。但这并没有提供答案。

try {
        object = (Dev)Class.forName("Dev").newInstance();
    } catch (Exception e) 
    {
        throw new RuntimeException("Devis not available");
    }
    finally
    {
        return object;  
    }

但是finally block 发出警告:

finally block does not complete normally

但根据我的轻描淡写，finally block 总是会被执行并返回对象。为什么警告说无法正常完成？

Answer 1

问题是finally block 会删除任何抛出的异常，因为它会发出“正常”返回。

来自JLS spec :

Abrupt completion of a finally clause can disrupt the transfer of control initiated by a return statement.

和(与您的情况更相关):

Note that abrupt completion of a finally clause can disrupt the transfer of control initiated by a throw statement.
