AtomicKeySetImpl.Externalizer.readObject() invokes a GetKeysInGroupCommand with a new context, but if a transaction is already running on the same thread it will reuse the transaction. Since tx contexts are just a wrapper over the CacheTransaction, looking up entries for the GetKeysInGroupCommand modifies the parent invocation context as well.

Every time an AtomicKeySetImpl is read in a transaction and then passivated before commit, the externalizer thus adds the members of the group in the parent transaction's context:

testng-test: Committing {AtomicKeySetImpl.Key{group=key1, key=second}=VersionedRepeatableReadEntry(58cf8f94){key=AtomicKeySetImpl.Key{group=key1, key=second}, value=second component of object with key=key1, isCreated=true, isChanged=true, isRemoved=false, isExpired=false, skipLookup=true, metadata=EmbeddedExpirableMetadata{lifespan=-1, maxIdle=-1, version=NumericVersion{version=0}}}, key1=VersionedRepeatableReadEntry(66c38e51)

{key=key1, value=AtomicKeySetImpl{keys=[AtomicKeySetImpl.Key{group=key1, key=first}, first], added=[second], removed=null}, isCreated=false, isChanged=true, isRemoved=false, isExpired=false, skipLookup=true, metadata=MetaParamsInternalMetadata{params=MetaParams{length=1, metas=[MetaEntryVersion=NumericVersion{version=2}]}}}}

testng-test: Adding entry AtomicKeySetImpl.Key{group=key1, key=first} : VersionedRepeatableReadEntry(fabb651){key=AtomicKeySetImpl.Key{group=key1, key=first}, value=first component of object with key=key1, isCreated=false, isChanged=false, isRemoved=false, isExpired=false, skipLookup=false, metadata=EmbeddedExpirableMetadata{lifespan=-1, maxIdle=-1, version=NumericVersion{version=2}}}

Interesting enough, the Iterator-based iteration in EntryWrappingInterceptor.commitContextEntries doesn't throw a ConcurrentModificationException after this modification (at least in LocalDeltaAwareEvictionTest). It only started failing after I replaced the iterator with HashMap.forEach().
