Subject [jira] [Commented] (JSPWIKI-659) NotSerializableException on Tomcat restart , UserManager not Serializable
Date Sun, 13 Jan 2013 12:50:12 GMT

    [ https://issues.apache.org/jira/browse/JSPWIKI-659?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13552187#comment-13552187
] 

Glen Mazza commented on JSPWIKI-659:
------------------------------------

Does this problem occur if you shut down Tomcat properly instead of using Ctrl-C?  (i.e.,
by running $CATALINA_HOME/bin/shutdown.sh?)  If no, then I'm not sure this is really a problem.
 We can't and shouldn't be guaranteeing proper working of webapps, either on startup or shutdown,
if you shut down the servlet container improperly.  Proper shutdown is what allows webapps
to properly release their resources before closing.

> If you stop Tomcat using ctrl-C and restart it again, there is a NotSerializableException
on the console. Looks like this has no consequences, but still it should not be.
