---------------------------------------

Github user zjureel commented on the issue:

    https://github.com/apache/flink/pull/4455
  
    1. For the `StateBackendITCase`, it can be resolved by bumping the tycho 
compiler version to 1.0.0, but when I try to use tycho compiler version 1.0.0 
in `flink-java`, it will cause lambda exception for `LambdaExtractionTest`. I 
think it's better to stay in the same version of tycho compiler in different 
flink project, so I try to modify the code of StateBackendITCase to resolve the 
problem directly.
    
    2. For the `JobRetrievalITCase`, I try every version of tycho compiler, the 
problem always exists. I think tycho compiler may be incompatible with 
`Seq.last()` method. I try to use another method in `Seq` to get the last 
element in `JobRetrievalITCase`, and it would be ok
    
    @zentol What do you think? Thanks :)
