Jianxia Chen commented on GEODE-1460:
-------------------------------------
Threads are not properly synchronized. One thread just created the
ccnSingleton, but before it created haContainer (haContainer is still null at
this point), the other threads read the null haContainer, which resulted in a
NPE.
> RemoveAll fails with NPE in
> com.gemstone.gemfire.internal.cache.tier.sockets.CacheClientNotifier.checkAndRemoveFromClientMsgsRegion()
