Bazel 5 is going to be a second long term support release.
Changes from bazel_4:
- compile java_tools (such as ijar) using nix-provided jdk
- local jvm and jdk are now passed using --tool_java_runtime_version, --tool_java_runtime_version and --extra_toolchains flags
see https://docs.bazel.build/versions/5.0.0/bazel-and-java.html for details
- update-srcDeps.py: distdir_tar function renamed to _distdir_tar to properly parse bazel query output executed against bazel 5 sources
- bazel_5.updater: uses bazel_4 to generate src-deps.json. This change was required to handle json.decode calls in bazel 5 dependencies
- protobuf-test and java-test adjusted to take into consideration both jdk 8 (for Bazel < 5.0.0) and jdk 11 (for Bazel >= 5.0.0)
