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 `java.lang.instrument.ClassFileTransformer`'s `transform` method.
