Currently JBoss/JCA has no support for handling 'stale' connection conditions wherein a JDBC connection fails during use. The ValidConnectionChecker is only executed prior to use or in the background as of JBoss 4.0.5. Shutting of exception sorting in this situation is a bit drastic in that no exceptions would be seen as FATAL anymore. This feature would add the capablity of handling a stale connection and permit an application to retry SQL executions that may have failed under certain conditions.
