Native executable (not working with AWS CRT)

[Silaszur]

Describe the bug

When I create a native executable with GraalVM using aws-iot-device-sdk-java-v2 (for subscribing to a aws topic), and execute it, I get the following:

Unable to unpack AWS CRT lib: java.io.IOException: Unable to open library in jar for AWS CRT: /windows/x86_64/aws-crt-jni.dll
java.io.IOException: Unable to open library in jar for AWS CRT: /windows/x86_64/aws-crt-jni.dll

When I create native executables with packages other than aws packages, I have no issues.
I was also able to get the aws-crt-jni.dll from the aws-crt jar manually from the jar file, so I don't understand why I am getting this.
When I run my Subscriber the normal way it all works
I am pretty new to all of this and can't seem to find a fix.

Any help to resolve this issue would be greatly appreciated.

Expected Behavior

I expect to be able to create a native executable and run it without getting:

Unable to unpack AWS CRT lib: java.io.IOException: Unable to open library in jar for AWS CRT: /windows/x86_64/aws-crt-jni.dll
java.io.IOException: Unable to open library in jar for AWS CRT: /windows/x86_64/aws-crt-jni.dll

Current Behavior

Whenever I execute the the native executable I get:

Unable to unpack AWS CRT lib: java.io.IOException: Unable to open library in jar for AWS CRT: /windows/x86_64/aws-crt-jni.dll
java.io.IOException: Unable to open library in jar for AWS CRT: /windows/x86_64/aws-crt-jni.dll

Reproduction Steps

Any sample using software.amazon.awssdk.crt to create a connection with mqtt and creating a native executable with it.

GraalVM is not something that we have tested to use with this sdk. This might be a feature request to add support for this. That being said I have a few questions before trying to reproduce this.

What version of Java are you using?
What version of GraalVM are you using?
What are the steps to reproduce this Unable to unpack error? (more details the better)
