> 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}
