> The globalCacheClass (and the blacklist) is inefficient in the new classloader.
> 1) It only caches the Loader not the class
> 2) Because of (1) it goes through the classloader scheduling everytime
> 3) When the parent is not a ClassLoaderDomain (e.g. it is the system classloader) there is no real caching
> of the parent classes when useLoadClassForParent=true which is the default in this case.
> For import-all=true, this needs changing to something more like JBoss-4.x where the classes are cached directly
> and the parent classes get cached also when the parent is not a ClassLoaderDomain.
> With the most important being the cache/blacklist checked before the lock is taken on the classloader.
