Can you provide some more details, please? It isnt possible to tell what’s going on based on your description.

Can you post a minimal reproduction of the problem. Maybe the source code of a Java class which causes the issue?

Ok, that is good. dgraph4j consumes the following dependencies for compilation:

   // The production code uses the SLF4J logging API at compile time
    compile "org.slf4j:slf4j-api:1.7.21"
    compile "org.slf4j:slf4j-simple:1.7.21"
    compile "io.grpc:grpc-netty:${grpcVersion}"
    compile "io.grpc:grpc-protobuf:${grpcVersion}"
    compile "io.grpc:grpc-stub:${grpcVersion}"

So as you can see, it’s fairly minimal. I am not sure what could be possible reason for conflicts.

Closing this for now. But let us know if you think there is something we need to do on our end.
