[FineGrainedAtomicMap] Class Cast Exception in Clustered + Repeatable Read + Write Skew

Test case available in here [1]

When a transaction commits, the write skew check performs the validation by casting the cache entry to a ClusteredRepeatableReadEntry. However, the entry is a DeltaAwareCacheEntry.

This happens when you have operations over a map inside a transaction.

The tests failing are:
WriteSkewFineGrainedAtomicMapAPITest.testSizeOnCache()
WriteSkewFineGrainedAtomicMapAPITest.testCreateMapInTx()
