> I use NotificationBus channel and in the member joined method I call, bus.sendNotification(Node) - passing a custom Node object. Upon this I get the following error on the newly joined member,
> javax.crypto.IllegalBlockSizeException: Input length must be multiple of 8 when decrypting with padded cipher

> I could reproduce the same problem using NotificationBusDemo.java in JGroups 2.5 CR1. Here is what I did, 
>  
> 1) Generate a keystore using JGroups' KeyStoreGenerator  (I also tried with JDK 1.6's keytool to generate secret key)
> 2) Add the following line in the protocol stack of NotificationBusDemo.java in the main(),  
> "ENCRYPT(key_store_name=jgroups.keystore;store_password=storePassed;alias=mykey):" + 
>  
> 3) Add the following line in the memberJoined(..) method of NotificationBusDemo.java  
> bus.sendNotification("Member Joined");  
>  
> 4) Run 2 instances of NotificationBusDemo.java 
> 5) You'll get the following error message, 
>  
> > 3828 [WARN] ENCRYPT.up(): - exception occurred decrypting message 
> javax.crypto.BadPaddingException: Given final block not properly padded 
> at com.sun.crypto.provider.SunJCE_h.b(DashoA12275) 
> at com.sun.crypto.provider.SunJCE_h.b(DashoA12275) 
> I am running this on Windows using JGroups 2.5 CR1.  The original thread for this issue is at,
