Hi Michael, Alan,
This is a very small change to fix a problem in native code where, if
multiple threads are executing the native method, an unset value of a
static variable may be used. When setting static variables in a block
we can only be sure they are all set when the last one is. This is a
common pattern in the socket impl native code.
I plan to clean up this area of native code and remove unnecessary
duplicate static state, but for now I just want to resolve this
specific bug.

Thanks,

The proposed change will help but I assume it is not bullet proof. A
slightly better fix might to be do the initialization if nis_addrsID or
ia_addressID is NULL. I know I've mentioned this to you before, but I
think it would be a lot better to just replace this code with a cleaner
implementation in java.
