Description

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]
