Mule flow - java.lang.IllegalAccessError：尝试从类sun.nio.cs.UTF_8ConstructorAccess访问类sun.nio.cs.UTF_8

Question

我尝试启动应用程序时遇到此错误

ERROR 2015-11-12 10:47:14,521 [main] org.mule.module.launcher.application.DefaultMuleApplication: null
  java.lang.IllegalAccessError: tried to access class sun.nio.cs.UTF_8
  from class sun.nio.cs.UTF_8ConstructorAccess

知道为什么吗？我能够通过重新安装工作室来修复它，但它重新浮出水面。 请帮忙。

我的配置xml -
