[Bug swing/27203] New: document updates with active documentfilter may cause exceptions

[thebohemian at gmx dot net]

Code like this will fail when the Document has an active DocumentFilter which
absorbs the inserted text:

---

// Insert new text.
doc.insertString(start, content, null);

// Set dot to new position,
dot = start + content.length();
setCaretPosition(dot);

---

The problem is that the pre-calculated caret position may not be valid because
the DocumentFilter may have caused that.

First thing is to find out how the RI handles such cases (eg. where does it
place the caret) and then find all occurences of code like this. Unfortunately
this may be spread across different classes: JTextComponent, JTextField,
JTextField and probably DefaultEditorKit (the TextActions within it).
