Selecting text inside JTextPane(dragging the cursor) and passing the
last character throws following exception:

Exception occurred during event dispatching:

Small testing application is created in JBuilder3 by simply adding
JtextPane to a JFrame, without any intervention in the code.
Is this a bug and what can be done to avoid this?

Thanks.
