Plattrom is Linux x86_64, eclipse 3.7.1

executing following code:

public class Commit extends Git {
protected Process runShell(String arg) throws IOException {
Display firstDisplay = new Display();
Shell firstShell = new Shell(firstDisplay);
firstShell.setText("First Example");
firstShell.setSize(200, 100);
firstShell.open();
while (!firstShell.isDisposed()) {
if (!firstDisplay.readAndDispatch())
firstDisplay.sleep();
}
firstDisplay.dispose();

return Runtime.getRuntime().exec(
System.getenv("ASTA_PLUGIN_SH") + " commit " + arg + " xxx");
// ("/home/lutz/tmp/test.sh" +" " + arg);
}
}

causes the eclipse application to crash:
