   > spark profile compilation has error
   
   commons-lang3 3.13.0 is compiled using JDK8, 3.14.0-3.16.0 is compiled using 
JDK21, 3.17.0 is compiled using JDK17
   
   Because JDK21 is used for compilation, there will be more `MethodParameters` 
in the class file, which triggers a bug in the lower version of scala.

   ```bash
   javap -v Pair
   ```
