Camel Not Sending Objects in Headers to RabbitMQ

[Caleb Skidmore]

Hello,

When I set a header as an object and route it to RabbitMQ, the header does not 
arrive.  For instance:

List<String> testData = new ArrayList<>();
testData.add("test");
testData.add("data");
exchange.getIn().setHeader("ObjectHeader", testData);
exchange.getIn().setHeader("StringHeader", testData.toString());

When I check the headers in RabbitMQ, the StringHeader is there but the 
ObjectHeader is missing.  Any thoughts on what is happening to the ObjectHeader?

Thanks,
C
