B4J Question Bouncycastle strange behaviour

Good morning,

after doing the client certificate implementation (as described in the B4J Code Snippet section) I ran into a massive issue and i can't figure out what's going on.

The exact code as posted in the Snipped area does work in Windows, the Jar can be started via double click, via shell or via B4J GUI in debug and release mode. This is all good and how it shoud be.....

In MACOS I can start the Jar via CLI. The App dies immediately if I double click the JAR but I can execute via B4J GUI in debug and release mode mode.

In Ubuntu it is even more strange. executing the JAR via shell, double click or Bridge I always will get:

If I remove the BC part from the code the JAR runs on all systems.....
B4X:
MqttConnectOptions1.RunMethod("setSocketFactory",Array(jo.RunMethod("getSocketFactory", Array As String (cafile, certfile, keyfile, keyFilePassword))))


I am sure it is related to Boucycastle but I can't figure it out :(

who has an idea whats wrong ??


THX a lot :)

here is the MacOS log after the crash via double click the Jar......it is 'identical' to the Linux one

It is indeed missing from your app.

You need to the dd or replace the library with bcpkix jar: https://www.bouncycastle.org/latest_releases.html

yes, if both are declared it works....:D

B4X:
#AdditionalJar: bcprov-jdk15on-163
#AdditionalJar: bcpkix-jdk15on-164


to be honest i don't quite understand what the difference is if it is started from the CLI or by double click....
Why does it work without bcpkix-jdk15on-164 when run from CLI?

THX
