"Illegal character in port number" errors in itests

[tadayosi]

While looking at the recent CI itest failure on itests-netty, I found the following errors occuring frequently in many itests. Why is it happening? Can we fix this?

I haven't researched further on this one, but it appears to be a problem on when the Jetty on the Kafka Connect shuts down. It may be possible that the way we are setting it up for execution in the embedded instance is affecting its behavior during the shutdown.
