Multiple selection using the shift key isn't possible at some cases - If the tree contains both modifiable and non-modifiable nodes. There is private boolean ignore; flag at org.eclipse.gef.ui.parts.TreeViewer class which determines whether the selection should be done or not. When you try to do multiple selection with the help of the shift key at modifiable nodes of the tree the method private void showSelectionInTree() is called two times. First time the private boolean ignore flag is true and second time is false. But first time should be false and second time should be true. This causes the shift key has similar behaviour like ctrl key.

Reproducible: Always

Steps to Reproduce:
1. Create some Eclipse plugin which uses Outline.
2. Create some content of the Outline with the help of org.eclipse.gef.ui.parts.TreeViewer class (nodes are non-modifiable and leafs are modifiable). Set edit domain for the TreeViewer.
3. Run the plugin and try to do multiple selection from leaf to another leaf with the help of the shift key. Shift key works in the way of the ctrl key (but it works well from node to node because the nodes are non-modifiable).
