[Bug swing/26843] New: JTextArea with lineWrap=true - selecting text across multiple lines cause IllegalArgumentException

Type

abc
def
ghi

into a JTextArea with line wrap enabled, go before the b and press shift-down
(should select the text from b to d). On Classpath this causes the following
exception:
