hazecast-client not OSGI-ready anymore since 3.1.6 - osgi

Question

I've been struggling with class loading problems using hazelcast and OSGI (equinox), that I hope have been fixed with Version 3.2-RC1 (ClassLoaderUtil).
My Problem now is that since Version 3.1.6, the hazelcast-client artifact's manifest does not contain any bundle information anymore, same with 3.2-RC1.
I couldn't find any reason for this in the issue tracker so I guess it's an error?
My workaround to use 3.2-RC1 on the cluster nodes an 3.1.5 on the clients (where I don't have class loading issues) does not work, I'm getting this exception:
15:54:41.002 ERROR [hz.node1.cached.thread-1 ] ClientEngine - [127.0.0.1]:5701 [dev] [3.2-RC1] Unknown field name: 'cId' for ClassDefinition {id: 2, version: 0}

Answer 1

You're right, it seems that bundle informations are missing on hazelcast-client.jar. I'm looking into it to fix it as Peter said for 3.2.

Answer 2

The client version needs to be exactly the same as the server version. So you can't have a 3.1.5 client in combination with a 3.2-RC1 server.
If there is an issue with the manifest file, please open a ticket here:
https://github.com/hazelcast/hazelcast/issues
And we'll get if fixed before the 3.2 release.
