Cache.putForExternalRead in DIST transactional mode is not replicated to other members

Since the context is non transactional, no command is enqueued in the transaction's modification list to be replicated at prepare time and also TxDistributionInterceptor does not explicitly replicate the command to other owners immediately after local execution. The command end up executing only on originator. This bug seems to be caused by the DistributionInterceptor class hierarchy refactoring in 5.2.
