切换 contextClassLoader 应该使用 try finally 恢复之前的上下文

val oc = Thread.currentThread().contextClassLoader
try { 
   Thread.currentThread().contextClassLoader = jvmPluginClasspath.pluginClassLoader 
   ImageIO.scanForPlugins() 
   NativeDB.LIBRARY.load() 
} finally {
   Thread.currentThread().contextClassLoader = oc
}

因为在此处修改contextClassloader会影响onEnable的调用者是么？ 有道理
