Description Andy Wilkinson 2019-04-17 07:26:27 UTC 
This is a follow-on from https://bz.apache.org/bugzilla/show_bug.cgi?id=60152.
When a connector is added to StandardService it calls Connector.start() if the
service is available. If the connector throws an exception it is caught, logged, and swallowed [1]. This prevents an embedder from handling the exception.

Could a similar change to [2] please be made that makes it possible for an embedder to catch and handle the exception themselves?

I was going to complain, but ContainerBase.addChildInternal has a template for that.
