The test doesn't have a history of (flaky) failures that I've discovered, and I
haven't gotten it to fail locally.
The NPE comes from a null return from {{v.getCoordinator()}}.
{code}
synchronized (registrants) {
if (isCoordinator) {
coordinator = localAddress;
if (v != null && !v.getCoordinator().equals(localAddress)) {
logger.info("This member is becoming coordinator since view {}", v);
v = null;
}
}
