Method Details

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 aClassFileTransformer
'stransform
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.
-
getClassLoadingLock
This class loader is not parallel capable so lock on the class loader rather than a per-class lock.- Overrides:
