org.apache.bcel.generic.StackProducer

- Packages that use StackProducer
  Package | Description
  --- | ---
  org.apache.bcel.generic | This package contains the "generic" part of the Byte Code Engineering Library, i.e., classes to dynamically modify class objects and byte code instructions.
  org.apache.bcel.verifier.structurals | Provides a PassVerifier class mostly used internally by JustIce, yielding a control flow graph for public use as a nice side effect.
