```
public ParallelWebappClassLoader copyWithoutTransformers()
```
    Returns a copy of this class loader without any class file transformers. This is a tool often used by Java Persistence API providers to inspect entity classes in the absence of any instrumentation, something that can't be guaranteed within the context of a ClassFileTransformer's transform method.
    The returned class loader's resource cache will have been cleared so that classes already instrumented will not be retained or returned.
    
    Returns:
    the transformer-free copy of this class loader.
