I am getting the Core dump on Linux box. I have a Request /Reply pattern implemented and it crashes when the program calls the .recieve() method.It occurs sporadically. Did anyone face this issue?
Here is the dump for your reference.

Did you? |
I did. The website is restructured after Oracle took it and could not find such forum in it. I was completely lost yesterday night trying to find this forum. |

LOL... found the culprit. But the reason appear to be silly though.
I have a line in my code where I typecast the recieved message
msg = getReplyConsumer().receive(5000);
BytesMessage tempMsg = (BytesMessage)msg;
The receive() is returning NULL due to timeout. The very next line, I am trying to cast it to BytesMessage. I expected it to throw an Classcast exception since it is null. Instead it is causing core dump.  When I put a null check before casting, it works fine. |
