As it would be, since it is no longer connected to the
database. However, your Java application doesn't know that the
connection is gone; so finding the exact point at which the crash
occurred would be hard.

No; and because it isn't happening on your Windows/Superserver
installations it's happening either (or both) because it's Classic
and because it's Java.

I suggest reposting your question on the firebird-java list, since
it's much more likely you'll find someone there using your
combination of OS and driver.
