If a simpler configuration based solution is desirable, we could simply offer the use of the calling thread's context classloader, instead of requiring the caller to provide a classloader. This would be accomplished via a boolean configuration attribute and the startService() method would make the appropriate registration. We wouldn't need to provide a classloader attribute.
