Current Behavior
Java lambda fails to load files from /var/task/META-INF/services directory.

the files under /var/task/META-INF should have the right permissions
How are you starting LocalStack?
With a docker-compose file
Steps To Reproduce
This is docker compose file:
version: "3.7"
services:
localstack:
image: localstack/localstack
networks:
- test-network
ports:
- "127.0.0.1:4566:4566"
environment:
- "SERVICES=lambda"
- "LAMBDA_DOCKER_NETWORK=test-network"
- "DEBUG=1"
volumes:
- "/var/run/docker.sock:/var/run/docker.sock"
- "$PWD/infrastructure.sh:/etc/localstack/init/ready.d/infrastructure.sh"
- "$PWD/target/deploy-package/lambda.jar:/tmp/lambdaa.jar"
networks:
test-network:
the shell script to create the lambda fucntion (infrastructure.sh)
awslocal lambda create-function \
--function-name my-function \
--runtime java17 \
--zip-file fileb:///tmp/lambda.jar \
--handler Handler \
--role arn:aws:iam::000000000000:role/lambda-role \
--timeout 300 \
--memory-size 512
awslocal lambda wait function-active-v2 --function-name my-function
this is the error that i am getting when la,bda function starts:
SEVERE: Failed to read service files via classloader: /var/task/META-INF/services/io.grpc.NameResolverProvider (Permission denied)
java.io.FileNotFoundException: /var/task/META-INF/services/io.grpc.NameResolverProvider (Permission denied)

...
I also check the permissions of that specific file
INFO: Path: /var/task/META-INF/services/io.grpc.NameResolverProvider, Readable: false, Writable: false, Executable: false, IsDirectory: false
if i unzip and check the permissions that that file, i can see that that file has read permissions
