> OpenWebBeans initialization can represent a major portion of a Geronimo server's startup time. I've seen it take nearly 1/4 of a server's startup time. Nearly all of this time is caused because OpenWebBeans is using ServiceLoader.load(). 
> A search of wired bundles shouldn't be necessary (and we should avoid, if possible). We should be able to replace OpenWebBeans DefaultImplementationLoaderService with our own LoaderService implementation. This LoaderService implementation could in turn avoid the use of XBean's BundleClassLoader (BundleClassLoader.getResource() is what drives the getWiredBundle() processing).
