open class WeavingTransformer
ClassFileTransformer-based weaver, allowing for a list of transformers to be applied on a class byte array. Normally used inside class loaders.
Note: This class is deliberately implemented for minimal external dependencies, since it is included in weaver jars (to be deployed into application servers).
