On JDK 8 with your patches, we are loading around 4750 classes and

Hi David,
You could, of course this would have a minor impact on the whole thing,
in your custom ClassLoader, have an instance of:
final ConcurrentMap<Class<?>, Boolean> foundClasses = new
ConcurrentHashMap<>();
@Override
protected Class<?> findClass(String name) throws ClassNotFoundException {
...
...
if (foundClasses.putIfAbsent(clazz, Boolean.TRUE) != null)
races++;
return clazz;
}
Sure, but having this map puts me back in the same situation I was in
before where we have another concurrent map with a key per class.
