For the Java version of Gatling 3.14.3 on Windows, it works perfectly fine on X64 architecture, but I get an error " java.lang.UnsatisfiedLinkError no netty_tcnative" on an ARM64 windows machine using the Qualcomm Snapdragon X Elite cpu.
I did some research, and it seems like there might be a way to tell netty to use the JDK SSL library via
import io.netty.handler.ssl.SslContextBuilder;
import io.netty.handler.ssl.SslProvider;
SslContextBuilder.forClient().sslProvider(SslProvider.JDK);
Is there a way I can somehow work around this issue – admittedly it is not Gatling’s fault!
JVM:
java -XshowSettings:properties -version
os.arch = aarch64
Log messages:

Please correct me if I’m wrong, but it’s only a log and not a crash/blocking error. I’m going to lower the logging level from ERROR to WARN in a next release.
You can disable OpenSSL/BoringSSL usage in the gatling.conf file.
Note: I don’t expect Netty to provide BoringSSL binaries for Windows ARM any time soon, if ever. You can ask on their project then.
it logs this as INFO, but subsequently the build fails. Maybe I have a different issue?
I tried setting useOpenSsl = true in gatling.conf, that did not seem to have any effect.

[ERROR]
[ERROR] Re-run Maven using the -X switch to enable full debug logging.
Oh right, the check is implemented in 2 different places, and one of them is blocking.
cf Core: fallback to JDK SslProvider when OpenSSL is not available · Issue #4635 · gatling/gatling · GitHub
In the meantime, you’ll have to disable useOpenSsl when running on Windows ARM.
Thanks for reporting.
Thanks SO much!
This worked perfectly in gatling.conf for Windows arm64 !!!
useOpenSsl = false
