Java 11 warning for protobuf illegal reflective access

[antoniy]

We've doing a migration of our application to Java 11 and Spring Boot 2.1.0 and we get these warning messages in our logs:

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by com.github.os72.protobuf351.UnsafeUtil (file:/Users/user/.m2/repository/com/signalfx/public/signalfx-java/0.0.48/signalfx-java-0.0.48.jar) to field java.nio.Buffer.address
WARNING: Please consider reporting this to the maintainers of com.github.os72.protobuf351.UnsafeUtil
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

Not sure if this repository is the right one to reise the issue but I considered that we are using signalfx library and not protobuf so here should be the best place to report the issue.

I think that would be something to take up with the os72 shaded protobuf libraries that we use (https://github.com/os72) ?

We haven't looked at Java 11 support yet for signalfx-java.

+1 I'm using this in java 11

@mpetazzoni Protobuf fixed this in 3.7.0 according to protocolbuffers/protobuf#5549, and there is a shaded version of 3.11.1 at https://github.com/os72/protobuf-java-shaded-3-11-1. So I think signalfx-java can just bump these versions now (although there might be issues to resolve).

+1 for this.
