eclipse平台升级- 粘贴功能失效

     eclispe从3.3升级到3.7.2时出现粘贴功能不好使。以下是代码的对比：

  eclipse3.3中

Object destination = getTarget(javaElements, resources);

if (destination instanceof IJavaElement)
ReorgCopyStarter
.create(clipboardJavaElements, clipboardResources, (IReorgDestination) destination)
.run(getShell());
else if (destination instanceof IResource)
ReorgCopyStarter
.create(clipboardJavaElements, clipboardResources, (IReorgDestination) destination)
.run(getShell());

 
eclipse3.7中

Object destination = getTarget(javaElements, resources);

ReorgCopyStarter
.create(clipboardJavaElements, clipboardResources, ReorgDestinationFactory.createDestination(destination))
.run(getShell());

 
由代码中可以看出在eclipse3.7中，将destination 类进行了重组。在eclipse3.3中直接对模型进行匹配。例如

IJavaElement  IResource
