I'm planning to release 4.0 RealSoonNow(TM) as the development has progressed 
quite well. I'm not intending  to create a 3.2.2 release.

Hi [~tv] ,

is it possible to get a backport also for version 3.2.1?

Thanks,
Florin

Hi Florin,

I understand that this bug needs fixing. However I don't believe that 
LateralTCPListener is the right place for the fix. This needs to be addressed 
in IElementSerializer.deSerializeFrom() because this method is used in several 
places.

Please note that I will not fix this issue in the jcs3 release anymore but in 
jcs4.

[jira] [Commented] (JCS-244) JCS-LateralTCPListener dies and not automatically recovers

2026-03-05 Thread Florin POP (Jira)

Florin POP commented on JCS-244:


I have clear steps for reproduction now also outside WebLogic context.

Have a distributed cache on 2 nodes for example. Configure in the cache.ccf 
files that the listener port is 7800 for both nodes.
Start the 2 JVMs and in the beginning both are communicating, the 
*JCS-LateralTCPListener* can be seen up on both nodes.

In order to break one of the nodes and make the listener disappear, I did a 
telnet host2 7800 and just closed the session without sending anything.
At this moment I can se on the JVM from node 2 the exception:
java.nio.BufferUnderflowException
       at java.base/java.nio.Buffer.nextGetIndex(Buffer.java:721)
       at java.base/java.nio.HeapByteBuffer.getInt(HeapByteBuffer.java:498)
       at 
org.apache.commons.jcs3.engine.behavior.IElementSerializer.deSerializeFrom(IElementSerializer.java:210)
       at 
org.apache.commons.jcs3.auxiliary.lateral.socket.tcp.LateralTCPListener.handleClient(LateralTCPListener.java:679)
       at

       at

       at java.base/java.lang.Thread.run(Thread.java:1583)

and the *JCS-LateralTCPListener* thread is no longer alive, thus the caches can 
no longer communicate.
