    if (AstUtil.isStatic(node.getModifier())) {
        varIdCounter = 0;
    } else {
        varIdCounter = 1;
    }
    BlockStmt body = node.getBody();
    ParameterNode[] parameters = node.getParameters();
    for (int i = 0; i < parameters.length; i++) {
        ParameterNode p = parameters[i];
        visit(p);
        if (p.getType() instanceof ObjectType) {
            md.visitParameterAnnotation(i, getClassDescriptor(getNullableAnnotation((ObjectType) p.getType())), true).visitEnd();
        }
    }
    md.visitLabel(methodStartLabel);
    if (body != null) {
        visit(body);
        if (node.getType().equals(VOID_TYPE)) {
            md.visitInsn(RETURN);
        }
        md.visitLabel(methodEndLabel);
        try {
            md.visitMaxs(0, 0);
        } catch (Exception ex) {
            ex.printStackTrace(System.err);
        // throw new RuntimeException("exception when visit method:" + node.name, ex);
        }
    }
    md.visitEnd();
    return null;
}
