我正在使用Websphere应用程序server 8.5.5中的启动客户端来启动独立的java程序。它工作正常，默认classLoaderMode（PARENT_FIRST）。在websphere中运行launchclient与parent_last classloader模式8.5.5
但是，当我将其更改为PARENT_LAST并且未能初始化应用程序组件时。这是命令
> File to launch = C:\workspace\myapp.ear
> CC Property File = null
> Client Jar File = <default>
> Alternate DD = null
> BootstrapHost = localhost
> BootstrapPort = 2809
> Trace enabled = false
> Tracefile = null
> Init only = false
> Classpath Parameter = myjar.jar
> Security Manager = disable
> Security Manager Class = Not used. -CCsecurityManager=disable
> Security Manager Policy = Not used. -CCsecurityManager=disable
> Exit VM = true
> Soap Connector Port = null
> Application Parameters = --name abc
> Provider URL = null
> Dump Java Name Space = long
> Admin Connector Host = null
> Admin Connector Port = null
> Admin Connector Type = null
> Admin Connector User = null
> PARENT_LAST mode = true
这里是例外：

是什么导致IBM推出客户端加载并与PARENT_LAST类加载器模式失败了吗？我想知道它是否是一个Websphere应用程序Server 8.5.5。或者我只是不正确地运行它。
在此先感谢。
