Crash at WTK22 with streamConnection

public void run(){
throws IOException {
StreamConnection streamConnection = null;
InputStream inputStream = null;
StringBuffer b = new StringBuffer();
try {
streamConnection = (StreamConnection)Connector.open(url);


Everytime I reach the line
streamConnection = (StreamConnection)Connector.open(url);
the screen asking if I want to connect appears, and the WTK22 gets blocked and I have to close it

That line it's in a thread because WTK don't like to call connections in the CommandAction event :P
