A message is normally submitted two times to drools component:
- first as Active
- second as Done

A filter exist in DroolsEndPoint.handleProviderExchange in order to process only Active message but not enough in my case.

In my case the first pass was processed correctly the exchange then and in DroolsEndPoint.handleProviderExchange the second pass was still Active not DONE... then it fire the rule and when it arrive in jbiHelper.answer the exchange was passed to DONE, so when it try to set the OUT message it failed.

Solution is to add the same filter in jbiHelper.answer as it was done in DroolsEndPoint.handleProviderExchange like this :
public void answer(Source content) throws Exception {         
        MessageExchange me = this.exchange.getInternalExchange();               
        if (me.getStatus() == ExchangeStatus.ACTIVE) 
        { 
          ...
        }
}
