With this property set to false, the issue is no longer present.

Steps to Reproduce

1) Create WSRP-Enabled portlet via remoteable tags.

2) Add the following property to portal-ext.properties:

session.timeout.auto.extend=true

3) Edit web.xml for session timeout to be 1 minute.

4) Startup the portal, deploying both the WSRP-enabled test portlet and the WSRP plugin.

5) Upon auto-extend trigger, an exception is generated.

Test Environments
Unable to test, as wsrp plugins were not working with trunk/branch.
