Comment from David Jencks on rev 472993 and 472998:

You are assuming that any connector that
has a config-property called "Driver" uses that property for a java
class name that is expected to be on the classpath.  I can easily
imagine a jdbc wrapper for a specific database that has a "Driver"
config-property to choose between a type 2 and type 4 driver and e.g.
the property is an Integer rather than a class name.

I think we could either
-- emit a warning if the class can't be loaded rather than throwing
an exception
or
-- only do this check if we are loading the tranql generic jdbc
wrapper in some version.

> If you deploy the attached plan with the TranQL connector RAR, the distribute phase is successful, but it fails during start because the driver class is not available.
> It would be much better to find a way to validate the driver class during distribution.  I'm not sure how complex this will be; it may involve instanting things during distribution that normally aren't instantiated until start time.  But the current behavior is definitely not desirable.
