SpringFramework caches a missed TypeConverter used by Camel and user can not clean it

Issue

Once getProperties(String, Class) fails, it will never work for the same arguments.

camel route

@Override
public void configure() throws Exception {
  from("timer://foo?repeatCount=1")
  .bean(myBean, "setArrayList") // Set a correct Object
  .bean(myBean, "checkSampleProperty")  // It sould work    
  .bean(myBean, "setEmptyArrayList")   // Set incorrect Object
  .bean(myBean, "checkSampleProperty") // It should fail
  .bean(myBean, "setArrayList")  // Set a correct Object again
  .bean(myBean, "checkSampleProperty");  // It should work. But actually, it will return null.
}

myBean

public class SampleBean {

    private final static Logger LOG = LoggerFactory.getLogger(SampleBean.class);

  public void setEmptyArrayList(Exchange exchange) {
    ArrayList<Dummy> list = new ArrayList<Dummy>();
    exchange.setProperty("sample", list);
  }

  public void setArrayList(Exchange exchange) {
    ArrayList<Dummy> list = new ArrayList<Dummy>();
    list.add(new Dummy());
    exchange.setProperty("sample", list);
  }

  public void checkSampleProperty( Exchange exchange) {
    ArrayList list = (ArrayList) exchange.getProperty("sample");
    LOG.info("ArrayList size: " + list.size());
    Dummy dummy = exchange.getProperty("sample", Dummy.class);
    LOG.info("dummy object:" + dummy);
    }

}
