refactor: change notification params type from Map<String,Object> to Object#137
Conversation
…Object This change generalizes the parameter type for notification methods across the MCP framework, allowing for more flexible parameter passing. Instead of requiring parameters to be structured as a Map<String,Object>, the API now accepts any Object as parameters. The primary motivation is to simplify client usage by allowing direct passing of strongly-typed objects without requiring conversion to a Map first, as demonstrated in the McpAsyncServer logging notification implementation. Affected components: - McpSession interface and implementations - McpServerTransportProvider interface and implementations - McpSchema JSONRPCNotification record Signed-off-by: Christian Tzolov <christian.tzolov@broadcom.com>

Breaking change alert, but I think it's absolutely worth it.

Let's keep in mind to take note of the breaking change in the release docs. I think it's worth the effort though.
