复现方式

启动HugeGraphServer后，创建PK，VL、IL即可。

cause分析

HugeGraphServer启动后，taskExecutor（FixedThreadPool）虽然已近创建，但是其负责运行任务的线程还没有创建。当用Gremlin执行IndexLabel创建时，会产生异步任务rebuildIndex并提交至taskExecutor，此时会真正的创建一个新的Thread去执行rebuildIndex。而SecurityManager不允许Gremlin执行中创建线程，因此出现not allowed异常

由IndexLabel create出发rebuildIndex是系统内部的合理机制，SecurityManager应该允许。除了rebuildIndex外，还有以下合理的系统内部异步任务，这些都应该被允许创建Thread：

  • VertexLabel delete
  • EdgeLabel delete
  • IndexLabel delete
  • remove left indexes

因此，修复方式为：SecurityManager允许系统内部的异步任务调度时创建Thread。

没有在API test中添加测试用例，是因为没有想到好的方法能保证在server启动后且taskExecutor创建完Thread前，执行上述会触发异步任务的操作。
