[Native Image] Using Bouncy Castle provider ... again

[HarrDevY]

Describe the Issue

Hi,
I would really appreciate if someone could give a complete working example how to get bouncy castle running with native image. This issue has been discussed many times in past, but all post about it use deprecated code. You'll find a repository to reproduce this here:

https://github.com/HarrDevY/native-register-bouncy-castle

Steps to reproduce:

• use GraalVM 21.0.5
• run mvn -Pnative compile:native (will work fine)
• run application with target/registerbouncycastle
• execute a curl curl -i http://localhost:8080/encrypt?val=foobar

it will fail with error Trying to verify a provider that was not registered at build time: BC version 1.8. All providers must be registered and verified in the Native Image builder

Please point out by giving a working configuration or source code example how to fix this. Don't use any deprecated thinks like Feature ...

Thanks!

Using the latest version of GraalVM can resolve many issues.

Hi @HarrDevY,

Thank you for reaching out to us about this!
Could you please try retesting using the latest available version of GraalVM? you can find it here: https://github.com/graalvm/graalvm-ce-builds/releases/
Also can you please try using the tracing agent to generate the configuration files and then try testing again? More information on how to use it can be found here: https://graalvm.github.io/native-build-tools/latest/maven-plugin.html#agent-support

Hi @selhagani ,

generated configuration files are already part of the project: https://github.com/HarrDevY/native-register-bouncy-castle/tree/main/src/main/resources/META-INF/native-image
I will check latest with latest version, thanks.

I have a thread running with bouncy castle as well: bcgit/bc-java#2001

@winfriedgerlach suggested to use a Feature implementation and additional graalvm build args. I've updated my repo according to it. Now it works, but it includes GraalSDK artifact and requires -H:+AllowDeprecatedBuilderClassesOnImageClasspath build arg. Is there an other way to achive the same result?

@HarrDevY wasn't me, I think you mean @ligefeiBouncycastle ;-)

Oops, sorry. You are right 😊 The final version without using GraalSDK can be found im my repo. Thanks for your help.
