| * <p> |
| * This is caused by the {@link TypeConversionConfiguration} class registering a |
| * {@link TypeConverter} (of actual type {@link DefaultTypeConverter}) in the Spring |
| * {@link ApplicationContext}. Its '{@code public void shutdown()}' method is inferred as a destroy-method by <i>Spring</i>, |
| * which will thus be called before the {@link CamelContext} shutdown |
| * when the context is closed. |
| * <p> |
| * As a consequence, any inflight message that should be processed during the graceful |
| * shutdown period of Camel won't have access to any type conversion support. |
