UT015008: Failed to load development mode persistent sessions

jurej Jan 10, 2014 2:44 AM

Below is the error that i receive upon redeploying an application. I am using wildfly-8.0.0.CR1. I think the beta1 was not producing this. What is the cause of this and is there a way to prevent it.

It seems that wildfly is somehow trying to restore session but fails doing so. Is that a new feature?

Googling "ss.weld.context.CreationalContextImpls" returns ZERO results. Now thats something i havent seen for a while.

I'm also getting this stacktrace when redeploying.

ss.weld.context.CreationalContextImpls.war/W

I'm pretty sure it's a messed up classname somewhere. I think the fully qualified classname is org.jboss.weld.context.CreationalContextImpls (or some such) and for some reason it appears to be messing up the classname.

If either of you have a reproducible application, please create a WFLY JIRA WildFly - JBoss Issue Tracker and attach the application.

Hey guys!

Persistent sessions are new feature to enable faster development as it keep you session / application state between redeploys.

The warning (not error) you get just tells you that server was unable to restore session after redeploy, everything should still work but you lost your session after redeploy.

you can also disable this feature by removing <persistent-sessions/> element from undertow subsystem, servlet-container section.

We need to improve this persistent session work a bit, but your app should still work. And you can safely ignore this warning.

Thank you Tomaž.

This is indeed a warning and does not affect the application whatsoever. I was also able to turn it off with the setting that you pointed out.

What I'm interested in is the state od this functionality. I must say that this is something that I've been waiting for years and I would really, really be interested in using it.
How come it does not work? Is it just not ready yet? Does my project require some additional configuration? Should I wait or is there any possibility to start using this right away.

Thank you for your answer and best regards.

Hello,

I think this [JBMAR-163] ByteBufferInput read method don't use offset / Wildfly cannot load persistent session data - JBoss Issue Tra… is the right issue. I have the same ruin class name.
