Method Details

copyWithoutTransformers

public ParallelWebappClassLoader copyWithoutTransformers()

Description copied from interface: InstrumentableClassLoader

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.
