Description
ProducerCache.doInProducer() may be called with null exchange.
The javadoc says
/**
* Sends an exchange to an endpoint using a supplied callback, using the synchronous processing.
* <p/>
* If an exception was thrown during processing, it would be set on the given Exchange
*
* @param endpoint the endpoint to send the exchange to
* @param exchange the exchange, can be <tt>null</tt> if so then create a new exchange from the producer
* @param pattern the exchange pattern, can be <tt>null</tt>
* @param callback the callback
* @return the response from the callback
* @see #doInAsyncProducer(org.apache.camel.Endpoint, org.apache.camel.Exchange, org.apache.camel.ExchangePattern, org.apache.camel.AsyncCallback, org.apache.camel.AsyncProducerCallback)
*/
public <T> T doInProducer(Endpoint endpoint, Exchange exchange, ExchangePattern pattern, ProducerCallback<T> callback) {
The exchange is however never created, which may result in a null return from ProducerTemplate and a possible exception silently being ignored.
