   ### Issue description
   
在PluginFilter类中通过requiredRespBody()方法设置为true后，在插件中调用PostRequest..getUpstreamHeaders()方法会偶现(概率很高)报错java.lang.IndexOutOfBoundsException:
 null
   ### Environment
   
   - apisix-java-plugin-runner 0.4.0
   - apisix 3.2.0
   - apisix-dashboard 3.0.0
   
   ### Minimal test code / Steps to reproduce the issue
   
   1.通过apisix-dashboard创建路由使用ext-plugin-post-resp插件

   2.写一个简单的java测试插件，并且设置requiredRespBody()和requiredBody()都为true

   3.多次调用会发现很大概率会报错503
