我有基于Luna版本的RCP应用程序.迁移到Luna 4.4.2版本后，我发现以下错误
I have RCP application based on Luna release. After migrating to Luna 4.4.2 relase, I observe the following error
!ENTRY org.eclipse.e4.ui.workbench 4 0 2015-08-27 16:59:58.081

Root cause is
java.lang.ClassNotFoundException: org.eclipse.ui.internal.ide.application.addons.ModelCleanupAddon cannot be found by org.eclipse.ui.ide.application_
1.0.501.v20141111-1238.
我应该对Luna进行额外的发布吗?还是我有配置错误?在64位平台上会观察到此问题.RCP应用程序是基于xtext 2.8.4的DSL实现.
What I schould intstall to Luna Release additionaly? Or may be I have configuration error? This issue is observed on 64 bits platform. RCP application is a DSL implementation based on xtext 2.8.4

评论表明
您的工作区正在尝试加载
org.eclipse.e4.ui.workbench.addons.splitteraddon.SplitterAddon.如果
1)从4.3.x目标或
1) you have o.e.ui.workbench from master in your workspace when launching from a 4.3.x target or
2)如果要使用4.3.x打开现有的Luna工作区
2) if you are opening an existing Luna workspace with 4.3.x
在使用由较早版本创建的工作空间启动时，我有一个类似的例外.在我的情况下，工作区是使用4.4创建的，并且在该工作区上启动基于4.5的应用程序时发生了例外.
I had a similar exception when launching with a workspace that was created by an older version. In my case the workspace was created with 4.4 and the exception occured when launching a 4.5-based application on that workspace.
