> If Log4J2 is initialized with a configured Socket or Syslog appender, and the destination
socket is not open, a IOException is thrown within TCPSocketManagerFactory on the "new Socket(data.host,
data.port)" line.
> This exception results in either a NullPointerException thrown to the calling code, regardless
if if suppressExceptions is true or false. No reconnect attempt is made, regardless if reconnectionDelay
is set to a positive number.
> The socket can still be created by TCPSocketManagerFactory, but attempting to connect
to the socket should wait until the first logging statement so that reconnection retries may
be used.
