Java SDK, the only special thing about the pipeline is that it uses the
mentioned @RequiresTimeSortedInput. The stateful dofn then actually doesn't use
any timers itself, only timers wrapped in StatefulDoFnRunner. But there seems
to be no actual difference between how timers are set in user code an in
StatefulDoFnRunner.
