FULL PRODUCT VERSION :
java version "1.4.1"


FULL OPERATING SYSTEM VERSION :

 Window NT version 4.0

A DESCRIPTION OF THE PROBLEM :
In the JText Pane using the RTF editor kit, when the user UNDERLINE the multiple lines with some blank line in
between ,'.' dot is shown for blank lines. it seems the blank lines are also UNDERLINED


EXPECTED VERSUS ACTUAL BEHAVIOR :
Actual result
----------------
It shows '.' (Dot) for blank/new lines after underlining the text.

Expected result
-------------------
It should not show any '.' for blank/new lines after applying UNDERLINE style format.
Blank/new lines should be seen as blank only but when the user types any character on that blank lines,it should
take UNDERLINE style for that character.

REPRODUCIBILITY :
This bug can be reproduced always.
