-------------------------------------------------------------------------
I was not clear in the previous comment. Thinking again on this, there are
some places where we wait for the this.regions to be populated.
{code}
synchronized(regions) {
while(!regions.containsKey(regionInfo)) {
// We should receive a notification, but it's
// better to have a timeout to recheck the condition here:
// it lowers the impact of a race condition if any
regions.wait(100);
}
{code}
When we need to update the this.servers also along with this.regions then we
need to have some sync block. I agree with Anoop here.
