> 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
