It is curious though, because only Srp256 should work, and Jaybird
explicitly tests with only Srp256 as a possible plugin (as set from
Jaybird, my test Firebird installations usually have all plugins
listed). One reason I can think of is that your version of Java doesn't
support SHA-256 (although as far as I know all 'recent' versions support
it). This should log a message with "Hash algorithm SHA-256 not
supported by JVM".

Which version of Java (including vendor, eg Oracle, AdopOpenJDK, etc)
and which variant of Jaybird 4 are you using (jdk17, jdk18 or java11)?
