Hi,

I am interested in the work, that you are doing here. Question: I notice, that your patch provides changes in the native code. That makes me hesitant: Before I accept the PR, could you help me to setup a build environment, where I can test these changes.

Background: We are considering a new release. As of now, there are no changes in the native code, so we could (in theory) just copy the native files from the previous release. But, for a release, that includes this PR, we would need a running build environment, where we can produce the updated files.

If this is interesting to you, please contact me privately at jochen@apache.org.

Thanks,

Jochen

We really need to update our GitHub build to deal with the C sources...

We need to be able to tell GitHub builds that we need OpenSSL >= 1.1.1

I found a warning in Java CI / build (macos-latest, 8, false): ** WARN: Could not enable JNA; detected lib VERSION 0x10000000: Error looking up function 'ENGINE_load_rdrand': dlsym(0x7ff81e7bd070, ENGINE_load_rdrand): symbol not found

Maybe the OpenSSL in Github builds is 1.0.0

Changes look fine; however there are no tests
