[Bug AWT/19862] New: Swing JTextField fails with StringIndexOutOfBoundsException

["hendrich at informatik dot uni-hamburg dot de" <gcc-bugzilla@gcc.gnu.org>]

Entering text into a JTextField fails with an StringIndexOutOfBoundsException,
triggered by a problem in GapContent or AbstractDocument.getText().
Tested with gcc-4.0-20050130 snapshot and a current (2005.02.09) cvs
checkout of gui-branch-20040128:

java.lang.StringIndexOutOfBoundsException
   at java.lang.StringBuffer.substring(int, int) (/usr/lib/libgcj.so.6.0.0)
   at javax.swing.text.GapContent.getString(int, int)
(/usr/lib/lib-javax-swing.so.0.0.0)
   at javax.swing.text.AbstractDocument.getText(int, int)
(/usr/lib/lib-javax-swing.so.0.0.0)
   at javax.swing.text.FieldView.getPreferredSpan(int)
(/usr/lib/lib-javax-swing.so.0.0.0)


Testcase attached. Note that the calculator functionality is stripped off
to make the testcase shorter. (This is slightly unfair for gcj, because
the expression parser does work with gcj.)
