You quoted the javadoc there and that's precisely my point about something
looking wrong. If my interpretation of that javadoc and the java source code
is correct, `awaitTermination` is returning false after blocking (due to
timeout), and you are just sleeping the thread for 30 seconds. which is plenty
of time for that work to finish. then you call a hard `shutdownNow` which has
no effect really because there are no more tasks executed. `awaitTermintation`
requires a call to `shutdown` somewhere for it to ever return true (success).
if this was a problem for appveyor I suggest you update your branch with
the latest changes which should have fixed the problems we were seeing with
this test:
https://github.com/apache/incubator-tinkerpop/blob/tp31/gremlin-groovy/src/test/java/org/apache/tinkerpop/gremlin/groovy/engine/GremlinExecutorTest.java#L634-L638
Let's see if appveyor is happy with that change before we go to merge this.
