Description

Ignition.Start fails with an exception:

Failure in Java callback Apache.Ignite.Core.Common.IgniteException: Invalid array specification: MassTransit.Initializers.PropertyConverters.MessageDataPropertyConverter+<MassTransit-Initializers-IPropertyConverter<MassTransit-MessageData<System-Byte\[\]>\,MassTransit-MessageData<System-String>>-Convert>d__4`1

1. ResolveNonGenericType should skip all generic types when scanning assemblies
2. ParseArrayDefinition should be fixed

Workaround

Register SQL key and value types manually before starting the cache:

ignite.GetBinary().GetBinaryType(typeof(TKey));
ignite.GetBinary().GetBinaryType(typeof(TValue));
