Method o.n.m.java.project.PackageDisplayUtils.isEmpty()	calls FileObject.getChildren() in EDT.
The actual slowness was caused by java.io.File.isDirectory() and java.io.File.lastModified(),
the contents of the files was not read. The NTFS filesystem was under heavy load, probably.

Closing and reassigning to java/Project.
