研究方向
Start by reading the referenced Google Groups thread and Play issue #4159 for context on the problem and proposed fix. Then examine Finagle's codebase for reflection based API calls, particularly in the core module, to understand how class loaders are used. The fix likely involves adjusting class loader usage to avoid conflicts with Play's auto reloading. No active PRs exist, so this requires original implementation based on the discussion.
