Classloader leak in wildfly-camel ContextCreateHandlerRegistryService

Redeploying a simple SY application several times results in OOME when running Fuse 6.2.1 on EAP with a small metaspace.

Further investigation revealed that classloaders are leaking across redeploys. The classloaders are being retained in ContextCreateHandlerRegistryService$ContextCreateHandlerRegistryImpl's handler mapping.

PackageScanResolverProcessor only calls createHandlerRegistry.removeContextCreateHandler(classLoader, contextCreateHandler); but not removeContextCreateHandlers(ClassLoader classsLoader) which would remove the ClassLoader entries from the handlerMapping Map.
