Re: Singleton memory leak after redeploying.

[Lionel Farbos <li...@free.fr>]

Hi Rémy,

It's a very good news for all !!!
Until now, we used a CleanupListener to do such things, and webapps could use it or not. 
Now, Tomcat will do this automatically for us :-))

But I need some complements :
- this new feature will be integrated in Tomcat 3 ? Tomcat 4 ? Tomcat 5.0 ?
- in the clearReferences(), you put static and final fields to null; perhaps (?) this can have bad side effects on webapps ?...
  For example, if a thread is not stopped and envisage to do something when such static variable is null ...
  It's not a classic need ... but, perhaps, it is a real use case ?...
- So, will it be possible to configure this new feature on such contexts ?
- My webapps generally don't use commons-logging : they use log4J; so, LogFactory.release will throw an exception. No ?

In advance, Thank you.
Regards.
