Hi @tzulitai ! Thanks for testing also this.
The problem with the `CEP` failing test for `1.3` while passing for `1.2`
is that the semantics of the `followedBy()` changed between `1.2` and `1.3`, so
the expected results cannot be the same.
In `1.2`, `followedBy()` implied non-deterministic relaxed contiguity while
in `1.3` it is just relaxed contiguity. So for `1.3`, either change the
expected result to contain only one match with the `foo1` as middle element, or
change the pattern to have `followedByAny(middle)` (and in this case you have
to take the savepoint again).

> Project: Flink
> Issue Type: Test
> Components: State Backends, Checkpointing
> Affects Versions: 1.3.0
> Reporter: Tzu-Li (Gordon) Tai

> Fix For: 1.3.1

>
> Already with FLINK-6763 and FLINK-6764 we'll need to change the serialization
> formats between 1.3.0 and 1.3.x.
> We probably should add the stateful job migration ITCases for restoring from
> Flink 1.3.x now.
