java SUN次要代码309含义

Question

我有以下线索：

org.omg.CORBA.INTERNAL:   vmcid: SUN  minor code: 309  completed: No
at com.sun.corba.se.impl.logging.ORBUtilSystemException.workerThreadThrowableFromRequestWork(ORBUtilSystemException.java:6330)
at com.sun.corba.se.impl.logging.ORBUtilSystemException.workerThreadThrowableFromRequestWork(ORBUtilSystemException.java:6355)
at com.sun.corba.se.impl.orbutil.threadpool.ThreadPoolImpl$WorkerThread.run(ThreadPoolImpl.java:513)

你能帮我解释一下这个小代码的意思吗
