Bug 31970 Go To Resource missing files
M5 build - org.eclipse.ui module in source, rest in binary - in Package Explorer, - Navigate / Go To / Resource... - type sync (looking for synced.gif under org.eclipse.ui\icons\full\clcl16) - no match - type *.gif - it's missing all of the gifs in this folder My Package Explorer filter settings are not set to filter out non-Java elements. These files show up in the Package Explorer, but not in Go To Resource.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/packageview/GotoResourceAction.java
if (!filter.select(fViewer, parent, element))
					return false;
			}
			return true;
		}
	}
	public GotoResourceAction(PackageExplorerPart explorer) {
		setText(PackagesMessages.getString("GotoResource.action.label")); 
		WorkbenchHelp.setHelp(this, IJavaHelpContextIds.GOTO_RESOURCE_ACTION);
		fPackageExplorer= explorer;
	}
	
	public void run() {
		TreeViewer viewer= fPackageExplorer.getViewer();
		GotoResourceDialog dialog= new GotoResourceDialog(fPackageExplorer.getSite().getShell(), 
			ResourcesPlugin.getWorkspace().getRoot(), viewer);
	 	dialog.open();
	 	Object[] result = dialog.getResult();
	 	if (result == null || result.length == 0 || !(result[0] instanceof IResource))
	 		return;
	 	StructuredSelection selection= null;
		IJavaElement element = JavaCore.create((IResource)result[0]);
		if (element != null && element.exists())
			selection= new StructuredSelection(element);
		else 
			selection= new StructuredSelection(result[0]);
		viewer.setSelection(selection, true);
	}
