This seems to only work when the parameters are simple values such as
strings, integers, etc.  For example:

	public void testBodyOgnlOnAnimalWithOgnlParams() throws Exception {
		exchange.getIn().setBody(new Animal("tiger", 13));
		exchange.getIn().setHeader("friend", new Animal("donkey", 4));
		assertExpression("${body.setFriend(${header.friend})}", null);

Fails with org.apache.camel.NoTypeConversionAvailableException: No type
converter available to convert from type: java.lang.String to the required
type: org.apache.camel.language.simple.SimpleTest.Animal with value donkey

Is that a known limitation?
