Why eclipse resource is "(not open)"? [message #998955]

I have a project in eclipse workspace.

When I open this project as IJavaProject using the following code, I have the project "not open".

IWorkspaceRoot root = ResourcesPlugin.getWorkspace().getRoot();
IProject orig = root.getProject(this.projectName);
orig.open(null /* IProgressMonitor */);
orig.refreshLocal(IResource.DEPTH_ZERO, null);
this.javaProject = JavaCore.create(orig);

I opened the IProject with `open()` method, and refreshed manually using `refreshLocal`.
I have other resources not opened.

I tried "F5" to refresh the project, but it doesn't work.

What might be wrong? How can I open the resources?

I think you are confused about the resource being open and the java element being open. There should be no need to open the IProject as it is already open in the workspace (you can check with isOpen()). Opening the IJavaProject is different. Opening a Java element opens a memory buffer for the element's contents. JDT will automatically open java elements as you try to access the contents (and cache the information). See org.eclipse.jdt.core.IOpenable for more information.
