Description
CacheOperationsTest.testFunctional() checks that some keys do not exist in the cache by calling evalMany on a read-write map, but with a read-only lambda.
This creates a VersionedRepeatableReadEntry(value=null) in the tx invocation context, and BackupSenderImpl.filterModifications() sends that to the remote site as a PutKeyValueCommand(value=null). On the remote site this is translated as cache.put(key, null), which finally throws a NullPointerException:

There's no exception on the local node, maybe because entries with null values are not committed regardless of what their flags say.
