Oh I see, then yes I guess we could store it as a static variable. Might it not
be an inconvenient though? What port would we set it to? What if someone is
doing test runs and has something bound to the port we came up with? Maybe the
ideal solution would be to use a system property as well... we could allocate
the bogus port normally through the getAlternativePort() if no property is
defined, or simply use the static variable if one is defined as a property.
I'm a bit skeptical about too many system properties, as they are
inconvenient to maintain and use.
They're fine for special cases, but the test suite should run
"out-of-the-box" if possible.
Your concern about something running on the bogus port already is valid,
but we generally have the same issue with all ports we use - especially
when the user specifies a base port.
We could try to connect a socket to the bogus port when creating the
TestConfiguration, or maybe even when getBogusPort() is invoked, but I'm
not sure it adds significant value. On the other hand, maybe the extra
time spent doing so is negligible.
In my view, it is better to have a well-defined mechanism to get the
bogus port, instead of doing getPort() -1 or something like that. I also
think that the failure messages for connect tests should include the
port number that was used, this makes it easier to debug.
Does this make sense, or is there a better solution?

A-ha I see what you mean. This limit is indeed for suites.All, so indeed it
wouldn't come up when individual suites are ran.
I'm not sure what you meant by bogus port though?
The bogus port is a port where no Derby network server (or anything
else) is running.
It is used for negative connect tests and such, for instance trying to
ping a network server on a port where there is no network server.
