Research direction
Start by reproducing the error with the shown UserTools, @Tool, ChatClient, and streaming setup on spring-ai-bom 1.0.0-M6, then trace the reported MessageAggregator aggregation error. Done means the tool call completes without a NullPointerException when toolName is null.
Written by the indexing model from the issue text.
