I am using Hibernate OGM 5.1.0.Final and hazelcast-hibernate5 1.1.3 ( even checked with 1.2 ). The OGM compatible hibernate ORM dependency is 5.1.5 , which is present in POM.

The issue looked similar to the one reported here - https://github.com/hazelcast/hazelcast-hibernate5/issues/13 , however I cannot upgrade ORM to 5.2, since it is not supported by OGM yet. Please suggest if there is a solution/workaround for the issue.
Version 1.1.3 and 1.2 of hazelcast-hibernate5 depend on Hibernate version 5.0.9.Final. You might need to exclude that in your Maven configuration and declare Hibernate dependency with version 5.1.5 yourself.
It seems hazelcast-hibernate5 doesn't support Hibernate 5.1.5. So I have modified hazelcast-hibernate5 code to support Hibernate 5.1.5 and released a custom version which can be found here. Note that this is not available on Maven central and it's not an official release of the plugin, just a quick change to support Hibernate 5.1.5 for your use case. It means that you have to install it to your local Maven repository first (or embed the JAR directly to your project). You can see the changes I have made in this branch to examine the code, or build from the source yourself.
