Hi, Thanks for catching this. There was a tiny issue that is reproduced only when a CacheConfiguration is being initialized like in your example. I've done a hot fix and pushed changes into the master.
On your side you can initialized the configuration the way below to avoid the exception CacheConfiguration config = new CacheConfiguration(); Regards, Denis -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/UnsupportedOperationException-on-adding-indexed-types-to-a-config-object-tp2642p2653.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
