不向全局事务发起方的undolog表写数据,应该怎么查找原因

This issue has no description.

The issue names no files, tests, or entry points; its body is empty. Start by locating the Java sample that uses a global transaction and an undo_log table, then reproduce the missing write and compare the initiator's transaction flow with the expected undo_log result. Done means the cause is identified and the sample or diagnostic steps clearly demonstrate the fix.
