---------------------------------------
kl0u opened a new pull request #6449: [FLINK-9994][DataStream API]
IntervalJoinOp Context#getTimestamp() returns max timestamp.
URL: https://github.com/apache/flink/pull/6449
## What is the purpose of the change
Although the `Context.getTimestamp()` in the `IntervalJoinOperator` should
return the max timestamp between the elements in the joined pair, it currently
returns the one of the "left" element.
This is a remain from past versions of the code, as the timestamp of the
collector is correctly updated to the max timestamp between the ones in the
matched pair.
## Brief change log
The main change is in the `collect(T1 left, T2 right, long leftTimestamp,
long rightTimestamp)` of the `InternalJoinOperator`.
## Verifying this change
The tests that were testing this behavior were wrong and they are now fixed.
