Yes, but you could change the license anytime you wish making that not
the case. If the source code is not available anyone using the code
could potentially fall victim to unforseen events. I'm saying anyone is
trying to do anything nasty, but if the source code, all of it, is not
open the potential for problems is always there.

There is a stark difference between linking and accessing vendors
backend system using a standard protocol like JDBC. If Oracle
disappears, which I admit is unlikely, then I can use any number of
backend databases. If your centre decides that it's never going to
release the proprietary code, your funding gets cut, your team disbands,
then I find a problem in one of closed libraries then I'm not really in
a good situation. I'm screwed basically and any of the time I've
invested in the project could be lost.

Hermes only works with your closed libraries. If they adhered to
standard Java APIs that I could swap out for open versions I wouldn't be
concerned. But as far as I know you're the only one's who have the code.

Is there any particular reason for closing general packages like
properties and logging? Given the prevelance of things like
commons-logging and the Preferences API?

As a standard practice, if I don't have the source code I can't use it
solely for pragmatic reasons and safety.

In short, man creates for himself a new religion of a rational
and technical order to justify his work and to be justified in it.
