Reproduction Steps:

1. Deploy Marketplace and Web Form portlets
2. Deploy the attached SpringMVCTest web plugin that depends on Marketplace and Web Form portlets and uses PortalDelegateServlet delegating to Spring's DispatcherServlet.
3. Visit the link http://localhost:8080/delegate/users/synchronize
   Checkpoint: The plugin deploys correctly and you see the log message:

   Controller executed successfully.

4. Restart the portal
5. Visit the link http://localhost:8080/delegate/users/synchronize

Result:
Actual: You are redirected to portal welcome page and following appears in log:

13:42:23,689 WARN  [PageNotFound:1114] No mapping found for HTTP request with URI [/delegate/users/synchronize] in DispatcherServlet with name 'delegate'
13:42:23,752 WARN  [http-bio-8080-exec-10][code_jsp:130] {code="404", msg="", uri=/delegate/users/synchronize}

Expected: You see the log message:

Controller executed successfully.

Note: As Tomcat's FAQ says: "There is no expected startup order." (http://wiki.apache.org/tomcat/FAQ/Miscellaneous#Q27) In my environment the issue was reproducible, because Tomcat tried to deploy SpringMVCTest after Marketplace portlet, but before web-form-portlet. Due to this fact it may be possible that you won't be able to reproduce the issue with the above steps and test portlet.
