Bug 64634 Navigate/Show in/Package Explorer doesn't work
With build I200405281200, if I select a Java file in the Navigator in the Java Perspective and then choose Navigate/Show in/Package Explorer, the Package Explorer is shown but the java file from the navigator is not visible or selected (i.e. the view doesn't expand the project or folder containing the java file).
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/packageview/PackageExplorerPart.java
if (result.length() == 0)
			return wsstr;
		return PackagesMessages.getFormattedString("PackageExplorer.toolTip2", new String[] { result, fWorkingSetName }); 
	}
	
	public String getTitleToolTip() {
		if (fViewer == null)
			return super.getTitleToolTip();
		return getToolTipText(fViewer.getInput());
	}
	
	/**
	 * @see IWorkbenchPart#setFocus()
	 */
	public void setFocus() {
		fViewer.getTree().setFocus();
	}
	/**
	 * Returns the current selection.
	 */
	private ISelection getSelection() {
		return fViewer.getSelection();
	}
