Re: [Dev] [ESB] NPE with EIP guide sample.

[Chanaka Fernando]

Hi Ajith,

The scenario which you have tested is not correct. If you put 
mediator in the outSequence, since you are cloning the request and send to
2 back ends, ESB will get 2 responses and tries to send back 2 responses to
client and that is causing this exception. What happens is that ESB will
send back the first response and then release the connection. When it tries
to send back the 2nd response, If some other thread has already reused that
connection, the "request" will be null and that is causing the NPE.

If you are putting a  mediator in the outSequence, make sure you
aggregate the responses before sending the response back.

Re: [Dev] [ESB] NPE with EIP guide sample.

[Chanaka Fernando]

Hi Ajith,

I have already added a fix to the NPE and currently testing that. Just
wanted to let you know that this is happening due to a configuration issue.
The code was written assuming that this NPE cannot occur in proper
configurations. But there can be some edge cases where this can become
null. I am currently investigating on those.
