Issue running on Alpine

[joeldbit]

Describe the bug: Unable to create Bean
We're trying to use aws-crt with s3TransferManager and it runs fine on a local macOS env but when we deploy to our alpine 17 based base image the app can't do a maven build.

It's running on JDK 17 and we use an alpine 17 image as a base image.

Expected Behavior
Build success

Current Behavior
Reproduction Steps
run "mvn clean verify"

Possible Solution
No response

aws-crt-java version used
0.27.0

Java version used
17

Operating System and version
Using the os-maven-plugin recommended, this is the information I get about the platform
Detecting the operating system and CPU architecture

2353 [INFO] ------------------------------------------------------------------------
2354 [INFO] os.detected.name: linux
2354 [INFO] os.detected.arch: x86_64
2354 [INFO] os.detected.bitness: 64
2354 [INFO] os.detected.version: 4.14

2356 [INFO] os.detected.release.like.alpine: true
2356 [INFO] os.detected.classifier: linux-x86_64 

Based on this, I tried setting the classifier property to linux-x86_64-musl but this didn't affect the error at all.

Could someone please suggest something I could be doing wrong ?

Hi, thank you for creating the issue. You mentioned Alpine 17, but the os.detected.release.version is 3.14.3. The binaries for Musl were compiled with Alpine 3.16. Can you please try with an Alpine version >=3.16?

If the issue persists, can you please share exact Docker image and JDK, along with a small, reproducible sample that you are using, to help debug this issue further? Whether Glibc or Musl is used depends on the installed JDK, not the OS. You can also try setting aws.crt.libc to glibc or musl if the CRT is not detecting it properly.

Hi @waahm7 ! Thanks for the quick response. Can confirm that upgrading to an Alpine version >= 3.16 fixed the issue for us.
