CloudBees Replication Parent 2458

When a replica of an HA controller is asked to display information that can be rendered only by another replica, such as a running build it does not manage, it acts as a reverse proxy. Under some conditions, the connection to the second replica could fail, for example, with a java.net.BindException when all TCP sockets are consumed. The stack trace was printed to the HTTP response and displayed to browsers in such cases. Now, the regular Jenkins error page displays, which usually notes only a UUID of the exception, printing the stack trace to the system log.
