The test
  api/javax_swing/interactive/JTextAreaTests.html#JTextAreaTest0011
is meant to probe line wrapping in JTextAreas. There is a checkbox
in the test that enables the JTextArea feature that forces wrapping
to occur at word boundaries.

After starting the test, I selected the "Wrap at word boundaries"
check box. Then I entered the text:
    0123456789012345678901 abcdef
into the JTextArea so that the right edge of the JTextArea is
just to the right of the 'f'. Typing a 'g' after the 'f' made the
contents of the JTextArea look like:
    0123456789012345678901
          g
This is the bug. Typing an 'h' after the 'g' made the JTextArea
contain two lines:
    0123456789012345678901
    abcdefg
which is what should be there.
