When an exception is thrown from a @Converter it is not correctly handled by onException. The handler is receiving a RuntimeCamelException and not checking the cause when determining the best handler.

/////Converter
@Converter
public static LocalDateTime toLocalDateTime(final Object localDateTime)
{
  System.out.println("Converting to local date time");
  throw new IllegalArgumentException("Bad data");
}

/////Routes
Routes routes = new RouteBuilder() {

  @Override
  public void configure() throws Exception {
    onException(IllegalArgumentException.class).handled(true).to("mock:exception");
    from("direct:test").convertBodyTo(LocalDateTime.class).to("mock:end");
  }
};


/////Test
MockEndpoint endpoint = (MockEndpoint)
camelContext.getEndpoint("mock:end");
endpoint.expectedMessageCount(0);
MockEndpoint endpoint2 = (MockEndpoint)
camelContext.getEndpoint("mock:exception");
endpoint2.expectedMessageCount(1);

camelContext.createProducerTemplate().sendBody("direct:test", "test");

endpoint.assertIsSatisfied();
endpoint2.assertIsSatisfied();
