IIRC, the setting is the number of seconds before reporting a connection as leaked. So, because most of your connections should be very short-lived, it should probably work. I would typically suggest a larger number as applications often have more variability in their use of connections (so something more like 10 seconds, or a few minutes if the application generates reports). Applications could even have different pools with different settings for use in different use cases.
Unfortunately I cannot really help with the Glassfish migration as I have literally only used it over that past couple of days to assist with your issue. Good luck there. That might be a better topic for a Glassfish mailing list as opposed to this one. The suggestions I made were just general ones for migrating any text configuration from one version to another.
