Seems to be caused by the assert on:
openide.text/src/org/openide/text/UndoRedoManager.java:397
- the "add" does not happen when assertions are disabled.

More precise steps to reproduce: enable remove trailing whitespaces on all lines, create a new Java file with main method, create several (~10) new empty lines (with indent) behind the "TODO" comment, save, undo: exception (happened always to me, with -J-da). Does not happen when I removed the assert (kept the addEdit, of course):

         WrapUndoEdit wrapEdit = new WrapUndoEdit(this, edit); // Wrap the edit

Might be related to bug #225087 (happened while I was trying to reproduce that) and bug #225052.

We apparently need an "assert with side-effects" warning.
