AS5 hasn't been an active branch for many years.  I strongly suggest upgrading to a more recent release of WildFly.  You can direct any questions to one of the forums.

> I have JSF based web application deployed in Jboss 5.1 EAP server. Enabled the distributable tag for session replication across two jboss nodes with Apache web server for failover feature and my business requires Attribute level replication but the system throws NullPointerException.
> "Failed to replicate session java.lang.NullPointerException"
> Here is how did I configure jboss for session replication:
> jboss-web.xml:
> <replication-granularity>ATTRIBUTE</replication-granularity>
> web.xml:
> <distributable/>
> Expected: Session should be replicated without NPE.
> Actual: Failed to replicate session 9jYCBgKn2mIIVS2g8EzEzQ__.XXXX
> Failed to replicate session 9jYCBgKn2mIIVS2g8EzEzQ__.XXXX
> java.lang.NullPointerException

> if(MarshalledValueHelper.isTypeExcluded(value.getClass())) {
>     return value;

> Please let me know if you need more detail. Also, I am trying to reproduce the issue with sample application but could not able to do. Kindly, provide some suggestions.
