Claus Ibsen commented on CAMEL-3255:
------------------------------------
Hmm I still don't think its good to have synchronized blocks in the default
case.
type converters is a bottleneck and hence there should be no contention issues
at runtime.
Instead we should provide 2 kinds of type converters. The default, and the Lazy
version. Then the lazy can use synchronized blocks in the code.
> Add property to DefaultCamelContext to allow for lazy loading of the
> DefaultTypeConverter

> Key: CAMEL-3255

> Project: Apache Camel
> Issue Type: New Feature
> Components: camel-core
> Affects Versions: 2.2.0, 2.3.0, 2.4.0
> Reporter: Mark Ford

> 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.
