The exception not showing actually has to do with java.util.concurrent,
not Jython. When an exception is thrown by code run in an
ScheduledExcutionThreadService, there's no where for the exception to be
caught immediately, so concurrent can't just print it out to the console
because it isn't sure that you don't want to catch it. However, when
you call get on the ScheduledFuture returned by schedule, it throws an
ExecutionException if the scheduled code threw and exception while it
was running. The ExcecutionException thrown will return the original
exception from getCause.
