java.nio.file.Files#setPosixFilePermissions cannot be used under Native Image

[linghengqian]

Describe the issue
A clear and concise description of the issue. We recommend using the latest snapshot builds to replicate the issue as bugs are constantly being fixed in the master branch

• java.nio.file.Files#setPosixFilePermissions cannot be used under Native Image. I created a minimal reproducible unit test at https://github.com/linghengqian/graalvm-v2301-set-posix-file-permissions-test.
• More early tests are at java.nio.file.Files#setPosixFilePermissions cannot be used under Native Image #7390 and Add support for org.apache.shardingsphere.elasticjob:elasticjob-lite-core:3.0.2 graalvm-reachability-metadata#206 .

Steps to reproduce the issue
Please include both build steps as well as run steps

1. [e.g.: git clone --depth 1 https://git.myrepo.com/projectone ]
2. [e.g.: mvn clean package]

• Execute the following command on the new Ubuntu 22.04.3 LTS instance.

sudo apt install unzip zip curl sed -y
curl -s "https://get.sdkman.io" | bash
source "$HOME/.sdkman/bin/sdkman-init.sh"
sdk install java 17.0.8-graalce
sdk use java 17.0.8-graalce

git clone [email protected]:linghengqian/graalvm-v2301-set-posix-file-permissions-test.git
cd ./graalvm-v2301-set-posix-file-permissions-test/
./gradlew -Pagent clean test
./gradlew metadataCopy --task test
./gradlew clean nativeTest

Describe GraalVM and your environment:

• GraalVM version (latest snapshot builds can be found here), or commit id if built from source: [e.g. EE 19.3, CE 20.0, CE 20.1.0-dev-20200304_0848] CE 23.0.1
• JDK major version: [e.g.:8] 17
• OS: [e.g. macOS Catalina] Ubuntu 22.04.3 LTS
• Architecture: [e.g.: AMD64] AMD64

Thanks for reporting, issue was reproduced and we are looking into it

[hamzaGhaissi]

According to dev team, This is expected behavior. The example tries to set POSIX file permissions on a path assuming that the associated file system supports PosixFileAttributeView, and since the NativeImageResourceFileSystem does not, it correctly throws UnsupportedOperationException.
