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
return false;
		return fViewer.isExpandable(element);
	}
	void setWorkingSetName(String workingSetName) {
		fWorkingSetName= workingSetName;
	}
	
	/**
	 * Updates the title text and title tool tip.
	 * Called whenever the input of the viewer changes.
	 */ 
	void updateTitle() {		
		Object input= fViewer.getInput();
		String viewName= getConfigurationElement().getAttribute("name"); 
		if (input == null
			|| (input instanceof IJavaModel)) {
			setTitle(viewName);
			setTitleToolTip(""); 
		} else {
			String inputText= JavaElementLabels.getTextLabel(input, AppearanceAwareLabelProvider.DEFAULT_TEXTFLAGS);
			String title= PackagesMessages.getFormattedString("PackageExplorer.argTitle", new String[] { viewName, inputText }); 
			setTitle(title);
			setTitleToolTip(getToolTipText(input));
		} 
	}
