    Description

      I'm getting intermittent ambiguous method reference compilation errors. It seems like it's a real bug since the method is ambigious when the referenced generic types have been ereased. Though I'm not sure why this is not always failing, it should, but it's probably a bug in Javac. I'm running Eclipse and it consistently complains about it.

      Output from Maven:

      [ERROR] testRevertConfigurationChange(org.apache.ratis.server.simulation.TestRaftReconfigurationWithSimulatedRpc) Time elapsed: 0.108 s <<< ERROR!
      java.lang.Error:

      A fix (but ugly) would just to be to re arrange the arguments.
