> The loading of type converters was changed from a lazy loading to an up front loading in a Camel 2.2. See issue CAMEL-2392 for details. Accordingly to the logging, it takes approximately 300 millis for this process to complete. 
> The proposal is to allow the configuration of this loading strategy for cases where the initialization time of contexts is more important than the loading of type converters. The "lazyLoadTypeConverters" property on the context will default to false to preserve the current up front loading behavior as the default. If this value is set to true, then the loading of the type converters will happen when accessed.
