[jboss-as7-dev] Removing / disabling data-sources requires restart

[Jason Greene]

In theory yes, however practically its very difficult to know it's unused. Especially considering a JNDI lookup without a proper dep is possible.

We have a solution for socket bindings were we use on demand services, but data sources can't be trivially be made on demand, due to the way resource ref deps currently work. See what happens when you do a programatic lookup on a lazy infinispan cache using jndi to see what I mean

In the short term the best we could do is change disable to leave the pool but make it throw errors when it's used. Remove would still be hostile.
