I can not catch IOException

[weke]

I'm having problems with jakarta-tomcat-4.0-b1 (running on linux :)) and i can not get 
IOEXceptions at all.

Servlet code:

try 
{     
ObjectOutputStream out = new ObjectOutputStream(client.getSocket().getOutputStream());
out.writeObject(new Integer(1));
}
catch (IOException e) 
{
removeClient(client);
}

If client goes away, (browser is closed,etc...), execution of code stops to 
out.writeObject()  Servlet blocks there forever. 

client class is an instance of my own SocketWrapper class.

Any hints?
Thanks, weggi.
