Bugs you mean happen in JBoss as well as in other environments. It does not
really matter whether you use JTA or local transactions, since local
transactions are built on top of JTA. In most cases those bugs are releted
to so-called "fatal errors" in Firebird (for example, database integrity
check, bug check, server crash, etc.).

As I'm an "interested" person here, I stop commenting this thread and let
others help you to find the right decision. My feeling is that
JayBird+Firebird is stable to be used in production environment.
