Thanks Andrew. This is a much needed fix. However, it looks like
AbstractLifeCycle logs all exceptions as warnings, and I wonder if this
obscures more serious exceptions if they don't surface to the main thread. Do
you see other sources of exceptions that we may not want to avoid logging? (I
personally haven't run into any other than java.net.BindException)
