Fyi, it's not just FMW apps that require a (much) larger than the default code cache size. ;-)
Also realize that it's not generally obvious or trivial for a user, or administrator of a Java to know when or if their app is experiencing an out of code cache situation. Yeah, there's a message emitted when code cache is full, but realize not everyone sees it. And, how may that do know what to do about it.
Btw, +1 on the idea of having code cache grow organically.
