Bug 61878 Package explorer is filtering out plugin dependencies [package explorer]
Build 20040506 When expanding the Plug-in Dependencies container, it is counter-intuitive to hide project dependencies. These are shown in the build path wizard itself, when you expand this container. I would expect to see them all the time.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/packageview/ClassPathContainer.java
private IJavaProject fProject;
	private IClasspathEntry fClassPathEntry;
	private IClasspathContainer fContainer;
	public ClassPathContainer(IJavaProject parent, IClasspathEntry entry) {
		fProject= parent;
		fClassPathEntry= entry;
		try {
			fContainer= JavaCore.getClasspathContainer(entry.getPath(), parent);
		} catch (JavaModelException e) {
			fContainer= null;
		}
	}
	public boolean equals(Object obj) {
		if (obj instanceof ClassPathContainer) {
			ClassPathContainer other = (ClassPathContainer)obj;
			if (fProject.equals(other.fProject) &&
				fClassPathEntry.equals(other.fClassPathEntry)) {
				return true;	
			}
