[mmedenjak]

@leszko @mesutcelik any ideas on this one?

[tamilchiran]

Issue resolved after downgrading hazelcast version to 3.12.4 in module openshift with minor code changes.

[mesutcelik]

@hasancelik Have you had any issue when you worked on this recently?

[mmedenjak]

I'm fixing some code samples and I'll send a PR soon. I think this one is also fixed. The problem is that some of our plugins don't work with 4.0 which is used by most code samples.

[mesutcelik]

Thanks @mmedenjak !
