>             Project: JBoss Messaging
>          Issue Type: Bug
>          Components: JMS Remoting
>    Affects Versions: 1.4.0.SP3.CP14, 1.4.8.SP11
>            Reporter: Yong Hao Gao
>            Assignee: Yong Hao Gao
>             Fix For: 1.4.0.SP3.CP15, 1.4.8.SP12
>
>
> In the following Jiras:
> https://issues.jboss.org/browse/JBMESSAGING-1851
> https://issues.jboss.org/browse/JBMESSAGING-1876
> We've added three more fields in ClientConnectionFactoryDelegate
>  private long maxRetryChangeRate;
>  private long retryChangeRateInterval;
>  private long minTimeoutProcessTime;
> This will cause backward compatibility issues when JBM server talks to old clients that are not aware of those changes. To those old clients the three fields are marshalled but never read by client. This will cause marshal problems as shown in the following example stack trace:
