I am benchmarking our Bazel-based Scala compiler tooling on different JDKs and I see a significant loss of performance when upgrading from GraalVM 17 to 21 (539s -> 583s in...

ScalaPB uses fully qualified names for most classes in generated code. Descriptors are a notable exception: ``` def javaDescriptor: _root_.com.google.protobuf.Descriptors.Descriptor = ApiProto.javaDescriptor.getMessageTypes().get(1) def scalaDescriptor: _root_.scalapb.descriptors.Descriptor = ApiProto.scalaDescriptor.messages(1) ``` In this...

Unmanaged `scalaInstance` ends up on test framework's classpath when it shouldn't
