Soctt,
     Assuming this fix will be in 4.0.16, how soon will that be released?


We're starting on the regression checkout for it. So this week if everything goes well.

We are looking to upgrade to Resin 4. I would not want to have to do the upgrade in 2 steps (first to 4.0.15, and then to 4.0.16 with this fix). How long is the startup delay anyway?

It would really depend on the application. For Liferay (a pretty big Spring application) it was almost a factor of 10.

    I may have just hit this and fixed it (I need to verify the specific
    change - there are two.)

    Resin's classloader does some analysis and caching to improve
    resource/class loading performance. This speeds up Spring/Hibernate
    initialization considerably. Some of that caching was causing problems
    with GC, so it was reversed. I'll see how it can be fixed.
