It is also possible that it is the same JVM, but that JBoss applies its
own policy.

With Oracle Java 8 update 161 and higher, it is the default setting (it
might be different for other Java vendors than Oracle). However this
setting can be changed.

Changing this setting should work. Make sure there is no # before the
line, and you will need to restart Firebird after changing the setting
for it to work. The cause of the error itself is that Jaybird announced
it could use encryption, and then Firebird - if it requires encryption -
will reject the connection if Jaybird doesn't start encryption before
the connection phase is complete.

Otherwise it would be helpful to have more logs to see if there is
anything else that could cause this.

You're welcome!
