MyBatis Race Condition

This project can reproduce the race condition when MyBatis builds mappedStatements:

1. Set a breakpoint on line 709 of HashMap(Oracle JDK 1.8.0_321), and set the breakpoint pause mode to Thread, and set the breakpoint condition to: this.getClass().getName().equals("org.apache.ibatis.session.Configuration$StrictMap").
2. Start me.tianshuang.MybatisRaceConditionApplication in debug mode.
3. Whenever a breakpoint is reached, hit Resume Program and watch the console output, because table does not contain the volatile modifier, other threads may not be able to see the latest table reference in real time, so we may need hit Resume Program multiple times, and when other threads access the latest table reference and the migration of elements in the oldTab has not yet completed, org.apache.ibatis.session.Configuration.StrictMap#get will throw java.lang.IllegalArgumentException: Mapped Statements collection does not contain value for me.tianshuang.mapper.Mapper1.select1.

Example of breakpoint setting:
