Review comment:
Would you try creating a new test or renaming test method? Maybe you can
reproduce the exception as below.
Sorry about the Chinese character. Literally, it means *Error: Symbol not
found*
```

错误: 找不到符号
blackhole.consume(l_reflectivevisitdispatchertest0_G.testReflectiveVisitorDispatcherInvokeInstanceCachingUseMethodHandle());

符号: 方法
testReflectiveVisitorDispatcherInvokeInstanceCachingUseMethodHandle()
位置: 类型为ReflectiveVisitDispatcherTest_jmhType的变量
l_reflectivevisitdispatchertest0_G
