Hello, who could help me?
Application hangs itself up.
Procedure:
1. It comes NullPointerException exception.
2. Exception intercepted with catch(NullPointerException e)
3. with e.printStackTrace() comes only java.lang.NullPointerException, without stack !!!
4. The next step should be the actualization of the JLabel with
SwingUtilities.invokeLater( new Runnable(){ public void run(){label.setText("text");} } );
Application hangs itself up completely
Described procedure runs in the separate Thread. Error meets only if application for a long time runs (over 20 hours).
Run time environment: jre 1.3_02 von Oracle; Oracle 8i (8.1.7) and Oracle 9i Lite (5.0.2)
best regards
Sasha.
