             Summary: Intermittent ambigious method reference
                 Key: RATIS-703
                 URL: https://issues.apache.org/jira/browse/RATIS-703
             Project: Ratis
          Issue Type: Bug
            Reporter: Henrik Hegardt


I'm getting intermittent ambigious 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!

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