> the Activator in camel-core take care of loading the converters from bundles, we should
avoid  calling BaseTypeConverterRegistry.loadTypeConverters() in OSGi container, otherwise
due to no classloader was specified, see this code in OsgiTypeConverter
>             @Override
>             public Set<ClassLoader> getClassLoaders() {
>                 // we don't need any classloaders as we use osgi service tracker instead
>                 return Collections.emptySet();
>             }
> we'll get exception like
> Caused by: org.apache.camel.TypeConverterLoaderException: Failed to load type converters
because of: Cannot find any type converter classes from the following packages: [org.apache.servicemix.camel.converter]
