Spring AI Ability to react to exceptions thrown by @McpTool methods

Expected Behavior

There is a way for me to react to @McpTool methods throwing exceptions, e.g. to log them.

Current Behavior

There is no way to react to exceptions, they are turned into an MCP error response (great!) and then discard, losing all stacktrace and cause information (not great!).

Context

I'm trying to diagnose errors in an MCP tool and not having the errors logged makes it quite painful.

Part of the reason for this is that only exceptions that are of the class returned by AbstractMcpToolProvider.doGetToolCallException are turned into responses, but it returns java.lang.Exception, so everything is.
