Dear Igniters, I'm working on a bug in .NET code that handles transaction states (jira ticket <https://issues.apache.org/jira/browse/IGNITE-13296>). And I need a way to handle stopped grid exception, so I think it will make sense to throw a specialized exception type in this case instead of a generic IllegalStateException <https://github.com/apache/ignite/blob/d486f24b1be3f08e8b1e5e9992c4c8718e169299/modules/core/src/main/java/org/apache/ignite/internal/GridKernalGatewayImpl.java#L95> .
Any objections? Best regards!
