Lateral Cache does not work with multiple writes to same object: OOS does not get reset
---------------------------------------------------------------------------------------

                 Key: JCS-82
                 URL: https://issues.apache.org/jira/browse/JCS-82
             Project: JCS
          Issue Type: Bug
          Components: TCP Lateral Cache
    Affects Versions: jcs-1.3
         Environment: JDK1.6 
ALL Operating Systems
            Reporter: Nikunj Trivedi
            Assignee: Aaron Smuts


In a Lateral cache environment, If a mutable object is written to JCS multiple times, only
original copy is written every time by ObjectOutputStream of LateralTCPSender.
This seems to be a known issue as per some forums, but not fixed since it could not be replicated.

My case is as follows: Server A & B has a common mutable object (say StringBuffer) in
cache. 
JDK1.6 Server A:
StringBuffer obj=new StringBuffer("Initial");
jcs.put("key",obj);//This is visible to Server B
obj.append("Append");
jcs.put("key",obj);//This gets ignored, B still sees obj="Initial"

I recompiled with LateralTCPSender.RESET_FREQUENCY from 70 to 1, it works fine.

I suggest, either RESET_FREQUENCY should be 1 or use oos.writeUnshared.
