Hi Tim,
I've just tried the current nightly build
glassfish-3.1.1-b07-06_09_2011, and your fix for GLASSFISH-16747 seems
to have made an enormous change.
The heap usage of my application has dropped from 156 MB to less than 70 MB.
Thanks so much for working on this issue - I'm really looking forward to
the 3.1.1 release!
Best regards,
Harald
