List dependency requirements for Java

[laurikimmel]

While upgrading stellarstation-api version from 0.2.0 to 0.3.0 I saw some unexpected exceptions. Upgrading other GRPC related dependencies fixed my tests.

Relevant version updates

com.stellarstation.api:stellarstation-api:0.2.0 -> 0.3.0
com.google.auth:google-auth-library-oauth2-http:0.11.0 -> 0.16.2
io.grpc:grpc-auth:1.16.1 -> 1.21.0
io.grpc:grpc-netty:1.16.1 -> 1.21.0
io.grpc:grpc-protobuf:1.16.1 -> 1.21.0
io.grpc:grpc-stub:1.16.1 -> 1.21.0
io.netty:netty-tcnative-boringssl-static:2.0.17.Final -> 2.0.25.Final

Upgrading stellarstation-api version form 0.3.0 to 0.4.0 didn't reveal any issues - same dependency versions are working fine.

Thanks for reporting this, and apologies for the slow response. We'll be more careful about this in our future releases (basically our pre-release testing wasn't thorough enough on this occasion).
