Unable to copy and paste multiple files in Eclipse project explorer

One thing I often do inside a java IDE is to copy files from one package to another. The IDE (either Eclipse or NetBeans) does the refactoring automatically including renaming the package. I usually copy multiple files of mixed types (e.g., java source files, ant build.xml files, web.xml, etc) in one operation.

I recently found I can't do that in Eclipse project explorer (3.4.1 ganymede). I can only copy files of the same content type in one command. That is, I can copy-paste-refactor multiple java files, or multiple xml files from one package to another. But it would fail if I try to copy java source files AND xml files.

It seems the copying part failed. When I tried to paste files of mixed types, the files copied in the last command were pasted, not the one supposed to have been copied.

This has been working pretty well in NetBeans 6.1 and 6.5.
