Bug 72992 Projects View no longer properly handles opened/closed projects
The Projects View (Java Browsing) no longer stops displaying closed projects, nor does it display newly opened projects. Eclipse I20040831 (but been around since I20040817?) Linux, GTK2.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/browsing/JavaBrowsingContentProvider.java
private StructuredViewer fViewer;
	private Object fInput;
	private JavaBrowsingPart fBrowsingPart;
	private int fReadsInDisplayThread;
	
	public JavaBrowsingContentProvider(boolean provideMembers, JavaBrowsingPart browsingPart) {
		super(provideMembers);
		fBrowsingPart= browsingPart;
		fViewer= fBrowsingPart.getViewer();
		JavaCore.addElementChangedListener(this);
	}
	public boolean hasChildren(Object element) {
		startReadInDisplayThread();
		try{
			return super.hasChildren(element);
