While upgrading (3.2.x to 3.3.2 and 3.3.2 to 3.3.3), running bundle install immediately pops these notices out:

The dependency activerecord-jdbc-adapter (~> 1.3.2) will be unused by any of the platforms Bundler is installing for. Bundler is installing for x64-mingw32 but the dependency is only for java. To add those platforms to the bundle, run `bundle lock --add-platform java`.
The dependency activerecord-jdbcmysql-adapter (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for x64-mingw32 but the dependency is only for java. To add those platforms to the bundle, run `bundle lock --add-platform java`.

It displays this message for 30sec-1minute before continuing. The bundle eventually runs and does it thing without much issue.
