[Hsqldb-user] Problem with 1.7.2 RC 4

[Jose M. P. <jm...@cr...>]

Hi,

I'm trying to upgradte from 1.7.2 R C 1 to R C 4. My application launchs a
hsqldb server at the beginning, I'am using the next code to launch the
server and it works fine with R C 1.

 public boolean launchDBServer()
  {

        final String[] args = new String[]
            {
            "-no_system_exit",
            "true",
            "-database",
            "..\\database\\klmanagerdb"
        };
        // create new server
        final Server server = new Server();
        // start server in its own thread
        Thread serverThread = new Thread(new Runnable()
        {
          public void run()
          {
            try
            {
              server.main(args);
            }
            catch (Exception ex)
            {
              ex.printStackTrace();
            }
          }
        });
        serverThread.start();

return true;

    }

when i have upgraded to 1.7.2 R C 4 this code does not work, i got the next
exception:
