Hi Lance,
Overall, looks fine.
Typo "earleir" at line 569.
I agree with having two separate init methods, since initDriversIfNeeded()
conveniently separates the (safe) double-checked locking idiom from the actual
initialization legwork in loadInitialDrivers().
I'm not entirely convinced, however :-), that DCL is necessary, but I could see
that it might be helpful if some of these operations are called frequently.
Sorry if this had been discussed previously.

Hi Lance,
to me it's irritating, why there are 2 methods:
- initDriversIfNeeded()
- loadInitialDrivers()
I would combine both to one method.
Mandy had asked me previously about this and here was my reply
-----------------
The reason I had the two methods was to further reduce contention checking to
see if the drivers need to be loaded. getConnection gets called frequently so
I thought that not having the initial check synchronized would be more efficient
-----------------
I think the code gets harder to read if I have one large synchronized block
assuming I move everything from loadInitialDrivers into the existing
synchronized block in initDriversIfNeeded.
In lines 90 + 92 there are double spaces.
Thank you.

Hi all,
Looking for a review for this change to DriverManager to reduce the possibility on a
deadlock on <clinit>. that I have been discussing with Mandy.
The change removes the static initializer block as well as the synchronized
keyword from registerDriver.
