Spring Boot: Failed to instantiate [com.hazelcast.jet.JetInstance]

I'm running hazelcast-jet-spring artifact (not hazelcast-jet) v.0.6.1 on Spring Boot v.2.0.3.RELEASE and getting this error:

Caused by: java.lang.IllegalArgumentException: DataSerializableFactory[-45] is already registered! com.hazelcast.internal.journal.EventJournalDataSerializerHook$1@4a3e1b5d -> com.hazelcast.journal.EventJournalDataSerializerHook$1@587df3e4

com.hazelcast.internal.journal.EventJournalDataSerializerHook com.hazelcast.journal.EventJournalDataSerializerHook

It looks like 2 classes with the same name but located in different packages are in conflicting state. Could you please advise how to avoid this?

Thanks!

I had to use an explicit dependency to Hazelcast 3.10.

Solved!
