在mvcSetUp 启动加载 IOC bean，偶尔会出现创建bean失败的问题，但极大多数启动，都没问题的，不知道，这与加载的顺序有关吗？？
以下是我使用的过程：
@IocBy(type = ComboIocProvider.class, args = {"*org.nutz.ioc.loader.json.JsonLoader", "ioc",
"*org.nutz.ioc.loader.annotation.AnnotationIocLoader", "x.x.x.x"})
@Encoding(input = "utf8", output = "utf8")
@Modules(scanPackage = true)
@SetupBy(MvcSetup.class)
@ChainBy(args = "ioc/chain.js")
@Chain("mainChain")
@Localization("msg")
@Views(BaseViewMaker.class)
@Ok("json")
@Fail("json")
public class MainModule {
}
public class MvcSetup implements Setup {
public void init(NutConfig config) {
....
CommonContext.ioc = config.getIoc();
X.register(CommonContext.ioc.get(Y.class));
X.register(CommonContext.ioc.get(Z.class));
.....
}
}
package x.x.x.x.x
@IocBean
public class Y {
private K k= CommonContext.ioc.get(K .class);
....
}
package x.x.x.x.x
@IocBean
public class Z {
private H h= CommonContext.ioc.get(H .class);
...
}

疑惑的问题一：Y 和 Z 类基本都差不多的加载，为啥Y加载没问题，而Z加载偶尔报错。
