org.eclipse.persistence.internal.libraries.asm.CodeVisitor
A visitor to visit the bytecode instructions of a Java method. The methods of this visitor must be called in the sequential order of the bytecode instructions of the visited code. The {@link #visitMaxs visitMaxs} methodmust be called after all the instructions have been visited. The {@link #visitTryCatchBlock visitTryCatchBlock}, {@link #visitLocalVariable visitLocalVariable} and {@link #visitLineNumber visitLineNumber} methods maybe called in any order, at any time (provided the labels passed as arguments have already been visited with {@link #visitLabel visitLabel}). @author Eric Bruneton

         * Later, via reflection, the setNumAttributes method is called with the
         * correct number of attributes
