[Jzjkit-user] SocketException after Searchable.close(); in jzkit 2.0.1

[Tom T. <tom...@se...>]

Hello,

I am in the process of porting an application over from using jzkit 
1.2.4 to jzkit2 2.0.1.  Most everything works, but I am getting a 
SocketException when I close down the Searchable object (in my case the 
Z3950Origin).  I can reproduce the problem by adding "s.close();" as the 
last line of the testLOC() method of  your Z3950Test.java test case. 

=============
    for ( int i=0; ( ( e.hasMoreElements() ) && ( i < 60 ) ); i++) {
      System.err.println("Processing result "+i);
      Object o = e.nextElement();
      System.err.println(o);
    }
   
    s.close();
==============

The close is required to shutdown the search thread, unless I'm missing 
something.  If I remove it like you have in your test case, then I get a 
bunch of threads lying around.

Below is the log.  It looks like a close is encoded and sent, but the 
socket is closed before the response can be read.
