Bug 123783

Description Jan Ploski 2006-01-13 11:35:27 EST

There seems to be an undesired interference between "Delete Next Word" and
hyperlink highlighting in rare circumstances (easy to reproduce, though):

Steps to reproduce:

1. Create a new Java class.
2. Move caret to the very end of file
3. Enter "// String", so that "g" is the last character of the file
4. Select the "r" in "String"
5. Now move the mouse pointer over the word while holding CTRL to activate
   Java hyperlink highlighting
6. While still holding CTRL, press DEL

In addition to "r" being deleted, an error dialog pops up and the following
exception is logged:

"Delete Next Word" did not complete normally.  Please see the log for more information.
