I have an OpenOffice Java addon application. I’m calling SWT from an XActionListener. Loading of SWT is done dynamically using a special class loader. The SWT window displays well, but when I hit the close button of an SWT window I get an error. I’m attaching the error file generated by this error.

What is the meaning of this error?

My SWT code

 final Display display = Display.getDefault();
    final Shell shell = new Shell();
    shell.setLayout(new FillLayout(SWT.VERTICAL));
    shell.setSize(500, 375);
    shell.setText("SWT Application");
    final Browser browser = new Browser(shell, SWT.NONE);
    browser.setUrl(location);

    try {
        try {
            shell.open();
            shell.layout();
            while (!shell.isDisposed()) {
                if (!display.readAndDispatch()) {
                    display.sleep();
                }
            }
        } finally {
            if (!shell.isDisposed()) {
                shell.dispose();
            }
        }
    } finally {
        display.dispose();
    }

I figured out the issue. I was having a finally block in which I was forcing a system exit. When I commented out this line everything worked OK. It seems that exiting in this code portion causes my whole OOo addon to crash.

    } 
    catch (Throwable t) //NOPMD
    {
        ExceptionUtils.printRootCauseStackTrace(t);
    } 
    finally 
    {
        System.out.println("Done.");
        // log.info ("Exit {}", rc);
        //I commented line below and this resolved the issue!
        // System.exit(rc);
    }
