Review comment:
Sorry I'm not that familiar with this code, could you help me understand
the change?
I'm assuming that this `refreshActiveWork()` call ultimately calls
`GrpcWindmiillServier.send()`, so we're catching the error here and logging it.
This is an improvement because previously that situation caused stalled GetWork
streams?
Are there other places where we should be catching the
`IllegalStateException`?
