Hi Jeanfrancois,
First to clarify since you mention 'undeployed' - maybe you're implying
implicit undeployment
that might be happening during re-deployment but in any case this is
what I do:
1. Deploy app
2. Request app services
3. Deploy (same) app (again) ie no explicit undeployment
Secondly, I'm not sure if application is 'holding the classloader'
since the application uses
the jruby runtime libraries. I'm cc'ing Charles and Thomas, the jruby
developers how might
be able to shed light on your question.
Thanks
Ashish
