FULL PRODUCT VERSION :
java version "1.5.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-b64)
Java HotSpot(TM) Client VM (build 1.5.0-b64, mixed mode, sharing)


ADDITIONAL OS VERSION INFORMATION :
SunOS oman 5.9 Generic_117171-12 sun4u sparc SUNW,Sun-Blade-1500

A DESCRIPTION OF THE PROBLEM :
With java 1.5.0 exceptions are thrown if "orb.disconnect(servant)" is called.
Furthermore the connection to the server application is not freed (checked it with lsof (list open files) 4.73) and the port remains occupied.

This becomes a problem if clients (through a webapp and tomcat) are opening connections to the orb and they aren't removed properly with disconnect(): this leads to the effect that all ports on the machine running the ORB (omniOrb 4.0.3) are blocked after a certain time and no further connections are possible (the only solution would be to stop/start tomcat which frees all ports).

Exception which is thrown under jdk1.5.0 (no problem with 1.4.2_x versions):

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. create a connection to an orb/get a reference:
-----------------------------------
org.omg.CORBA.ORB orb = ORB.init(args, props);
// get the root naming context
org.omg.CORBA.Object obj = orb.resolve_initial_references("name");
NamingContextExt nce=NamingContextExtHelper.narrow(obj);
objRef = "whatever"Helper.narrow(nce.resolve_str("service-name"));

(where "whatever" is the Helper class created from the idlj compiler.)

2. do whatever you want to do....

3. if all work is done and you are finished with, release and clean up:
-------------------------------------------------
  if(objRef!=null){
    if(orb!=null){
      orb.disconnect(objRef);  // causes exception in java 1.5.0
      orb.shutdown(false);
      orb.destroy();
    }
    objRef._release();
  }
  objRef=null;
  orb=null;


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
- no exception thrown when calling orb.disconnect()
- that all connections are freed
result from lsof after orb.disconnect() ended in an exception:
# lsof -c java | grep oman.krinfo
java     1559 user400    8u  IPv4 0x3021db79548    0t32409        TCP guam:33649->oman.krinfo.ch:62522 (ESTABLISHED)

i.e. connections remain ESTABLISHED and ports are taken....
EXCPECTED RESULT SHOULD BE:
# lsof -c java | grep oman.krinfo

ACTUAL -
see above: connections remain ESTABLISHED, ports occupied

Release Regression From : 1.4.2
The above release value was the last known release where this 
bug was known to work. Since then there has been a regression.
