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 :)
