vmtool 解析通配符不准确

[WangJi92]

  public Object testParam2(List<? extends User> param) {
        return param;
    }

• 解析结果为 null ? 应该是 User ？

  vmtool -x 3 --action getInstances --className com.wangji92.arthas.plugin.demo.controller.CommonController  --express 'instances[0].testParam2({null})'  -c 6f54e410

• 正确的

  vmtool -x 3 --action getInstances --className com.wangji92.arthas.plugin.demo.controller.CommonController  --express 'instances[0].testParam2({@com.alibaba.fastjson.JSON@parseObject("{\"name\":\" \",\"age\":0}",@com.wangji92.arthas.plugin.demo.controller.User@class)})'  -c c212d8b
