While I was testing the persistency of my autobuild plugin by opening and closing the project I noticed that sometimes the project gets loaded at (or around) closing time.
When this happened the project looked closed but when I open it eclipse did not trigger my loading code as once should expect during opening of a project.
The stacktrace is pretty big with lots of repititions (I still thought it was best to dump the whole thing)
I'm not sure this is a CDT issue but adding a "is the project open" test to the isNewStyleProject implementations or even to the getProjectDescription may be a good workaround/solution.

I added a isOpen to the getProjectDescription and the problem persists
It seems using isOpen will not do the trick

	public ICProjectDescription getProjectDescription(IProject project, boolean load, boolean write) {
		int flags = load ? 0 : GET_IF_LOADDED;
		flags |= write ? GET_WRITABLE : 0;
		if (project.isOpen()) {
			return getProjectDescription(project, flags);
		}
		return null;
	}

I had this issue again and found a way to reproduce and fix the issue.
The fix is a change in CprojecDescriptionManager

	public boolean isNewStyleProject(IProject project) {
		return isNewStyleProject(getProjectDescription(project,  false));
	}

Should be changed to

	public boolean isNewStyleProject(IProject project) {
		return isNewStyleProject(getProjectDescription(project, false, false));
	}

How I Identified this problem.
The stacktrace showed isNewStyleProject was called for some reason.
I noticed it was called when the project is selected in the project explorer so I put a breakpoint in isNewStyleProject but that made my debug session hang.
So I changed isNewStyleProject to:

	public boolean isNewStyleProject(IProject project) {
		System.out.println("calling isNewStyleProject for project " + project.getName());
		return isNewStyleProject(getProjectDescription(project, false));
	}

This way I discovered isNewStyleProject is called several times when it is selected in the project explorer even when the project is closed.
Because getProjectDescription(project, false) translates to getProjectDescription(project, true, false) which means "load the project when it is not yet loaded" all closed CDT projects are loaded when they are selected in the project explorer.
The CDT project loading triggers events in Sloeber that bounce because the project is not open.

(I made a comment expressing concerns on the specific fix provided in #725)

Is it possible that some changes are being made without a workspace lock so that one thread is closing project at same time as another thread is trying to look something up, causing project to reopen?
