I've tried many ways, but I find some exceptions cannot make the spout re-emit. But in my work, I strongly need that, how can I do? I've tried to throw the FailedException, but it seemed useless. This is my code

 try { 
process.waitFor(); 
} catch (Exception e) { e.printStackTrace(); 
throw new FailedException(e); 
}

did you try throw new FailedException("..")? – LiozM Aug 07 '16 at 11:21
Yes, I've tried, but it didn't work. This is the code try { process.waitFor(); } catch (Exception e) { e.printStackTrace(); throw new FailedException(e); } – Niubility Aug 08 '16 at 03:52
You should edit your question instead of putting this additional information into a comment -- this keeps the question clean and easy to read. Nobody want to read all the comments. – Matthias J. Sax Aug 08 '16 at 09:21
OK, thx for your advise:) – Niubility Aug 08 '16 at 09:38
