    Hey,
    
    Sorry for not attending to this for a long time. It needed a rebase for the API of the
chaining. Now that I have updated that the test throws the following NPE:
    
    Caused by: java.lang.NullPointerException
    	at org.apache.flink.streaming.api.complex.ComplexIntegrationTest$MyTimestamp.getTimestamp(ComplexIntegrationTest.java:659)
    	at org.apache.flink.streaming.api.complex.ComplexIntegrationTest$MyTimestamp.getTimestamp(ComplexIntegrationTest.java:654)
    	at org.apache.flink.streaming.api.windowing.helper.TimestampWrapper.getTimestamp(TimestampWrapper.java:34)
    	at org.apache.flink.streaming.api.windowing.windowbuffer.SlidingTimePreReducer.afterEmit(SlidingTimePreReducer.java:71)
    	at org.apache.flink.streaming.api.windowing.windowbuffer.SlidingPreReducer.emitWindow(SlidingPreReducer.java:59)
    	... 7 more
    
    It would be nice if we could separate the individual tests, so it is easier to track an
exception like that. Maybe a solution similar to `MiltipleProgramsTestBase` for streaming
would do the trick.
    
    @szape, could you please do an update with these, then I'd merge it asap so that it does
not get outdated again. Thanks.
