Usage

From source file:org.apache.drill.exec.compile.bytecode.ReplaceMethodInvoke.java

public static void main(String[] args) throws Exception {

    final URL url = Resources.getResource(k2);
    final byte[] clazz = Resources.toByteArray(url);
    final ClassReader cr = new ClassReader(clazz);

    final ClassWriter cw = writer();
    final TraceClassVisitor visitor = new TraceClassVisitor(cw, new Textifier(), new PrintWriter(System.out));
    final ValueHolderReplacementVisitor v2 = new ValueHolderReplacementVisitor(visitor, true);
    cr.accept(v2, ClassReader.EXPAND_FRAMES);//| ClassReader.SKIP_DEBUG);

    final byte[] output = cw.toByteArray();
