   I totally believe you. but, if I don't comment out these two. I still saw the error.  I leave those to you to figure out why those matter.
   
   ```
   # If true, SkyWalking agent will save all instrumented classes files in `/debugging` folder.
   # SkyWalking team may ask for these files in order to resolve compatible problem.
   agent.is_open_debugging_class = ${SW_AGENT_OPEN_DEBUG:true}
   
   # The instrumented classes cache mode: MEMORY or FILE
   # MEMORY: cache class bytes to memory, if instrumented classes is too many or too large, it may take up more memory
   # FILE: cache class bytes in `/class-cache` folder, automatically clean up cached class files when the application exits
   agent.class_cache_mode = ${SW_AGENT_CLASS_CACHE_MODE:MEMORY}
   ```
   
   Likewise,  I set the following as `true`, or I set it as `false`. Either way, I won't see the error again. 
   ```
   agent.is_cache_enhanced_class = ${SW_AGENT_CACHE_CLASS:true}
   ```
   I wish I could only need to care this, but it alone doesn't solve the problem
   ```
   agent.is_cache_enhanced_class = ${SW_AGENT_CACHE_CLASS:true}
   ```
