-changed signature to throw <code>org.eclipse.jface.text.BadLocationException</code>
-in order to add support for better handling of invalid document
-positions. Only clients which extend (i.e. call super) this method will be
-broken. To fix the problem either catch the exception from the super
-call or change the signature in the extended method. The latter is
-suggested since clients should decide how to handle invalid document
-positions.<br>

- <li><span style="font-weight: bold; font-style: italic;">org.eclipse.ui.texteditor.TextEditorAction.canModifyEditor()</span>:
-added predicate method that checks whether the action's editor can be modified. The method calls different methods on the underlying editor depending on
-which interfaces the editor implements. The method will call <code>ITextEditorExtension2.isEditorInputModifiable()</code> if it is available. Modifing actions
-can call the method when updating their enablement state.<br>

- <li><span style="font-weight: bold; font-style: italic;">org.eclipse.ui.texteditor.TextEditorAction.validateEdit()</span>:
- added predicate method that checks and updates the modifiable state of the action's editor. The method calls different methods on the underlying editor depending on
- which interfaces the editor implements. The method will call <code>ITextEditorExtension2.validateEditorInputState()</code> if it is available. Modifing actions
- can call the method before running modifing the editor's content.<br>
-</li>
- <li><span style="font-weight: bold; font-style: italic;">org.eclipse.ui.texteditor.AbstractDecoratedTextEditor</span>:
- A new intermediate class layer has been added between <code>StatusTextEditor</code> and other editors, namely <code>TextEditor</code> and <code>JavaEditor</code>. The additional layer
- includes features found commonly in advanced editors (and especially source editors) such as:
- <ul>
- <li>a vertical ruler to display annotations, line numbers, and quick diff information</li>
- <li>an overview ruler</li>
- <li>current line hightlighting,</li>
- <li>and print margin display</li>
- </ul>
- Implementors of an editor may choose to extend <code>ExtendedTextEditor</code> instead of <code>TextEditor</code>.
