Something wrong with importing eclipse projects

Build 3144
I created a IDEA project named "eclipse", and imported an eclipse project as a new module.

Everything seemed fine until I found all eclipse based classes and packages were highlighted as errors. A project library named "org.eclipse.pde.core.requiredPlugins" was created with all necessary eclipse jars but didn't trig any jar parsing process.

I looked into the "eclise.ipr" file, and found all jars were declared like "" instead of "]]>".

Is this a bug ?
