scratching my head over camel mail component

[cbuxbaum <cb...@tradestonesoftware.com>]

Hi,

I am doing a straightforward call to the Camel mail component:

			Exchange exc = endpoint.createExchange();
			Message in = exc.getIn();
			in.setBody(failureEmailBody);
			Map headers = in.getHeaders();
			if (headers == null)
			{
				headers = new HashMap();
			}
			headers.put("From", this.fromEmailAddress);
			headers.put("To", this.emailAddresses);
			headers.put("Subject", "TECH PACK EXPORT SYSTEM ERROR");
			headers.put("contentType", "text/html");
			in.setHeaders(headers);
			if (log.isDebugEnabled())
			{
				for (Iterator it = headers.keySet().iterator(); it.hasNext();) 
				{
		           String key = (String) it.next();
		           log.debug("Key:" + key + ", Value:" + headers.get(key));
		        }
			}
			// create a producer that can produce the exchange (= send the mail)
			Producer producer = endpoint.createProducer();
			// start the producer
			producer.start();
			// and let it go (processes the exchange by sending the email)
			producer.process(exc);

In my logging, I see the to and from addresses being set, but I get this in
the logs:

Where is the header or the "to value" getting lost?  This works fine in my
own environment, but on a customer dev env they get this issue.  This is
running as a war under tomcat

Thanks,

I believe I know the solution, if not the cause.  Our customer is using an
much older version of JavaMail.  Must be that MimeMessage.addRecipients is
not behaving properly.
