> Key: GEODE-6630

> Project: Geode
> Issue Type: Bug

> {noformat}
> I noticed in some tests with following error logged in debug level:
> [debug 2019/04/10 11:25:52.904 PDT <RedundancyLogger for region TestRegion>
> tid=0x55] Unexpected exception in PR redundancy recovery
> java.lang.NullPointerException
> at
> org.apache.geode.internal.cache.partitioned.RedundancyLogger.run2(RedundancyLogger.java:154)
> at
> org.apache.geode.internal.cache.partitioned.RecoveryRunnable.run(RecoveryRunnable.java:59)
> at java.lang.Thread.run(Thread.java:748)
> Then I looked at the code that it's using:
> (this.allBucketsRecoveredFromDisk.getCount() > 0) in more than one places.
> The allBucketsRecoveredFromDisk is referecing to the object in
> PRHARedundancyProvider.
> But in PRHARedundancyProvider, it is using:
> public boolean isPersistentRecoveryComplete() {
> if (!ColocationHelper.checkMembersColocation(this.prRegion,
> this.prRegion.getMyId())) {
> return false;
> }
> if (allBucketsRecoveredFromDisk != null &&
> allBucketsRecoveredFromDisk.getCount() > 0) {
> return false;
> }
> So allBucketsRecoveredFromDisk could be null. We should alway use
> "(allBucketsRecoveredFromDisk != null &&
> allBucketsRecoveredFromDisk.getCount() > 0) " instead of
> "(this.allBucketsRecoveredFromDisk.getCount() > 0)"
> {noformat}
