Description

There are several methods in GridDhtPartitionTopologyImpl where correct checkpoint and topology readlock order is violated: topology lock is obtained first, and after this an initialization of CacheDataStore could be called under the checkpoint lock.
Affected methods:

• GridDhtPartitionTopologyImpl#localUpdateCounters
• GridDhtPartitionTopologyImpl#partitionSizes
• GridDhtPartitionTopologyImpl#printMemoryStats
