Affects Version/s: 2.3.3
Fix Version/s: 2.5.x
Component/s: Plugin - Portlet
Pluto Portal Version: 1.1.7
Servlet Container: Apache Tomcat/6.0.33 (cluster)
Java Version: 1.6.0_29 (Sun Microsystems Inc. - Java HotSpot(TM) 64-Bit Server VM build 20.4-b02)
Portlets running with the model driven interface are storing non serialized classes in the ognlvalue stack. The value stack is saved in the session in the saveStack method for the portlet state interceptor.
My Portlets that do not use model driven seem to have no serialization issues.
Sample application to replicate: https://github.com/ctwomey1/Struts2PortletExample
I have replicated this problem in a simple tomcat cluster (2 nodes using a simple config, with pluto as the portal environment). As well as in an IBM WAS /Vignette portal combo.
