Research direction

The issue provides no file or test name. Start by reproducing the Qwen/Qwen3-30B-A3B request from the linked steps under Java 21 and Spring AI M7, then trace the tool_choice/tools validation that produces the 400 error. Done means the behavior is explained and a focused fix or documented limitation is backed by a regression test.
