Different behaviour in starting up my programmed app

Question

Hi,
I have developed a little app (TelTool.app) with a listener (tcp) that will display some messages it gets sent from a client, very basic things (programmed using OSX 10.4, xCode and Java/Cocoa: Yes I know this is outdated). Whenever a call comes into my house, the client connects to all computers with TelTool.app and sends them the phone-nr. / address of the caller.
I've set the Target to "Release", built and executed TelTool.app from Finder: Everything is fine so far, The Dock icon bounces whenever a call is incoming. Now, I added the App to startup objects and restarted the computer. Now, the app crashes (it doesnt react) and I have to kill it and manually start it in order for it to work.
Why are there differences when I start an app from finder with double clicking and when I let finder start it at boot time? What could be the mistake?
Thanks!
Some of my main class MainWindow.java:
public void awakeFromNib() {
// Initialize Cocoa things
this.txt_zeit.setStringValue("");
// adjust buttons
adjustButtons();
// Listener starten
try {
_server = new Server(this,5182);
} catch (Exception e) { System.out.println(e); }
// Incoming call //
public void callIncoming(String number) {
// Add call to list
CallList.addCall(number);
txt_address.setString("...");
// Set title
txt_title.setStringValue("Anruf "CallList.currentlyChosenCall()" von "+CallList.numberOfCalls());
// Load most recent call (nr) to interface
loadCallToInterface(CallList.numberOfCalls());
// Adjust buttons
adjustButtons();
// Bounce Dock Icon
NSApplication.sharedApplication().requestUserAttention(1);
// In the end, grab address from remote server
CallList.grabAddressOfCall(CallList.numberOfCalls());
loadCallToInterface(CallList.numberOfCalls());
}
