Currently, there is no way to conveniently do this. Technically this falls under the JCA spec area of reauthentication support which is, to date, unimplemented though there is a JIRA task for it. The best solution at this point would be to tune each pool according to your usage patterns (ie allow more on app1 and scale down appx). Note, even credential based access would not really address the issue as separate pools would be created for each credential.
