As noted for that property, if hostInfo is set as a value for this
jdk.includeInExceptions then IOException thrown by java.net.Socket will
container additional information. Is this expected to work for all kinds
of connection issues related to Socket types? For example, I have a Java
program which creates a ServerSocket and (intentionally) binds it to
port which is already in use. I (as expected) keep seeing this exception:
It's only used when when when connecting a stream-oriented socket fails.
It could be extended of course although I would expect most servers have
some form of log so the information on the local address/port might be
there already.!
